Boiler "four" leakage phenomenon determines: whether the output of hot water, steam or thermal oil, and regardless of using coal, oil, gas, biomass or power industrial biomass water tube boiler suppliers, has the following "four", respectively, of boiler waterwall tubes, superheater tubes, reheater tubes and economizer tubes. It covers all four pipes of the boiler heating surface, the internal pressure of the working fluid bear, may be external to bear the high temperature, harsh environment corrosion and wear, excessive reconcile between water and fire, where the energy is concentrated is passed .
4 large superior protection systems protect the water steam industrial biomass water tube boiler suppliers steam boiler is provided with two pumps, run and standby. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Boiler plate with one or two level timing, should always be compared with each other, find instruction inconsistent, it must be corrected immediately. Each class should rinse water level gauge to determine its true level. And also has balanced water pipe poles can accurately capture level signal or alarm to the pump control. 1, a pressure protection when the boiler pressure exceeds the vapor pressure protection rating, it is necessary to chain protection: is shutdown, the system stops the combustion; nozzle can be replaced, a single stage or two stage combustion, the amount of oil can be adjusted. , thereby reducing the pressure to ensure the safe operation of the boiler. As water pressure protection with protective oil (gas) steam boilers, the use of multiple protection: (1) the pressure controller typically uses two pressure control pressure signal into an electric signal electromechanical conversion device, which is a function of the high and low pressure signals to electrical switches, and the automatic control circuit or an external interlock protection. Normal pressure controller and make electrical contact pressure gauge vapor pressure and overpressure alarm off burner limit is reached, the pressure controller adjusts single or double fire burning fire based on the actual pressure. For large burner, the fuel can be adjusted according to the amount of pressure, the pressure is always maintained in a stable operating state. (2) is the last line of defense to protect the safety valve of the boiler. When the boiler pressure exceeds the limit, according to the set pressure relief valve design, releasing exhaust pressure, in order to ensure the normal operation of the boiler. 2. Temperature protection is an important part of the process of the safe operation of the boiler, especially for steam boiler temperature regulation and protection. While achieving regulation and protection function of the hot water boiler superheater. Conventional boiler temperature protection means is a bimetallic temperature controller 3. Flameout protection against furnace explosion. Oil (gas) boiler must be equipped with flame protection device, and its function is combustion monitoring furnace (including an ignition when the ignition failure or extinguish combustion, typically re-ignited within five seconds, runs in one second, closed oil ( gas) solenoid valve, is opened concurrent silent alarm signal, the blower continues to operate at this time. after the furnace was purged of combustible residual gas, after purging two thirty seconds, the fan and various auxiliary power cut off, stopping the boiler operation.) by a flame monitoring device and control components. Flame monitor display function is to signal the presence of a flame or an interrupt from the control device. Its main purpose is a photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an ultraviolet or infrared type photoelectric conversion element, its working principle is converted to the corresponding light radiation intensity of the high current and low current. And a linear output state, the induced current is sometimes weak, and thus affect the controller amplification. 4. The self-locking power failure protection in case of sudden power failure, the boiler operation immediately closed self-locking, if the current power is restored, start at any time, must be reset to unlock in order to re-start the ignition. Imported monochrome color touch screen control system, fully automated operation. Having automatic water supply, water, over-temperature, over-voltage, automatic power failure alarm, leakage protection security systems.
Environmental situation is not optimistic that China has issued a number of environmental policy, the full range of safeguards ecological environment. Provinces are also actively to improve environmental protection, recently, Ningxia Hui Autonomous Region winter heating industrial biomass water tube boiler suppliers proposed implementation. details as follows.
"Clean heating embodiment of Ningxia Hui Autonomous Region (2018 Year - 2021)," recently released, "plan" put forward, Ningxia heating the status quo, to develop clean heating, the use of clean energy alternative to coal and dispersed living coal, reducing coal consumption and soot emissions, improve environmental quality in urban and rural atmosphere.
By the end of 2017, Ningxia urban and rural housing construction for heating a total area of 380 million square meters, of which the city building heating area of about 240 million square meters, rural buildings for heating an area of about 140 million square meters. Clean heating total area of about 180 million square meters, accounting for about 47% of the region's total heating area. Among them, prefecture-level city clean heating an area of about 120 million square meters, clean heating rate of about 75%; counties (cities, districts) Clean heating an area of about 50 million square meters, clean heating rate of about 62%; rural clean heating area of about 14.72 million square, clean heating rate of about 10%.
After the "plan" put forward, Ningxia, according to the "central heating mainly to the substitution of gas for coal as the first, supplemented by electricity instead of coal," the idea, according to local conditions, scientific planning, coordination implementation. City, county (district) the main city clean coal-fired co-generation, large-scale energy saving boiler central heating heat source as the basis for strengthening efforts to shut down within a small range of central heating boilers of coal. Promote cogeneration units and ultra-low emissions transformation of large boilers, improving the environmental standards.
In urban and rural interface and rural areas, in accordance with the principles of the easier issues first, and start cleaning centralized heating schools, kindergartens, hospitals and other public buildings start to play an exemplary role. The conditions of the area to promote gas boiler; encourage nearby collected plant biomass feedstock, biomass briquette forming process instead of bulk coal; encourage livestock waste, straw and other raw material for the biogas fermentation and purified, for clean heating; actively promote the development of geothermal resources as a centralized or decentralized heating heat source; support for residents to install solar hot water, electric heating equipment, such as housing, agriculture greenhouses, farms; do not have clean heating conditions actively implement clean coal alternative bulk coal.
"Plan" clearly, Ningxia will accelerate cogeneration, waste heat utilization, the cell set into a piece of construction heating boilers, focusing on the completion of the Western Xia thermoelectric (two) central heating, in Nanjing Tianyuan thermoelectric, Helan back pressure Heating Unit central heating and other projects, the completion of thermoelectric Zhongwei, Wuzhong thermoelectric, thermoelectric Dawukou LIUPANSHAN thermoelectric renovation project, to further expand the central heating area. City, county (district) heating should vigorously promote the "coal to gas," "coal to electricity", according to local conditions the development of renewable energy for heating, a pair of old, energy-saving secondary pipe network, heating network system to enhance efficiency.
Ningxia will be fully phased out small coal-fired boilers, coal-fired boiler to deepen the comprehensive compliance management, municipalities, county (district) urban area out of 20 tons of steam / hour coal-fired boilers. Yinchuan City urban area to total phase-out project cogeneration district heating pipe network covering all coal-fired heating boilers in the region. It does not have the "coal to gas," "coal to electricity" conditions in rural areas, to achieve clean coal production and warehouse distribution center full coverage, full implementation of clean coal alternative bulk coal.
Ningxia Hui Autonomous Region in the 2018-2021 four-year, with the full complement of winter heating boiler, will replace all cleaner energy boiler coal-fired boiler, to protect people's health.
Applications gas steam industrial biomass water tube boiler suppliers and hot water boiler: gas steam boiler including a steam boiler and hot water boiler two categories, under the policy from coal to gas, the use of gas steam boiler is also increasingly widespread up. Regional gas boiler is also engaged in the implementation of replacement or renovation project. Well, today Dakai heat families come to you simply steam boiler applications have what? Steam boiler applications can be roughly divided into three categories, residential, commercial and industrial, civil and generally refers to the domestic gas boiler our lives with so-called boiler, primarily for home heating and bath with hot water , which is characterized by simple structure, convenient operation, long life, is the choice of most families choose; commercial, then generally refers to the star hotel, hospital school district heating mechanism, the general will choose to steam bath or gas boiler boiler for hot water supply of the main ways. Required in this area to select a gas boiler, characterized in that the gas or gas compared in terms of biomass fuel, no dust combustion, emissions in the flue gas can also control the amount of nitrogen emissions. Gas-fired steam boiler combustion more fully in value, mostly in the commercial is also a good choice; the last is the industrial furnace, industrial furnace is characteristic of large tonnage, high fuel demand, in general, the company received the heat a gas pipeline to gas as fuel, then the biggest advantage is that no storage, reducing transportation and storage costs of fuel, generally used for thermal power generation or industrial heating and heating company needs large industrial enterprises. Common gas boiler combustion gas steam boiler or hot water boiler refers to a common heating furnace heating boilers by natural gas as the main fuel, a common gas boiler furnace boiler there are two types of gas steam boiler and hot water system . Today Dakai heat families came to introduce lower furnace gas-fired boilers and other combustion What is the difference in the way, hoping to help you better understanding of gas-fired boiler. Gas steam boiler and the gas hot water boiler is a difference in combustion, most of this type are suspension burning, a combustion chamber for combustion-type layer, which is not generally furnace volume substantially less 20t, a commercial or civilian-based. In regulating the use of fuel is also more automated, and gas hot water boilers generally using boiling combustion, there is a kind of combustion whirlwind two different combustion, natural gas than other fuel burn advantages over when when the high temperature flue gas cooling furnace burn burn further cooling, the relative air speed greatly improved, not only to strengthen the burning, but also further enhance the thermal efficiency of hot water boilers, less cooling, but also conducive to the loss of gas. With gas as boiler fuel type on operating costs and emissions is still a great advantage. We all know that the price of gas is the most cost-effective boiler operation for a class, but on the discharge of nitrogen gas boiler seriously exceeded standards, coupled with the dusty, needs someone to maintain and so on. So more and more people choose to abandon the use of gas-fired boiler to select gas steam or hot water boiler. Future development condensing gas boiler obvious advantages
