If there is damage in the supposed gas-fired? Detailed inspection is important, as the key oil regulation. According to the conditions and time management, gas-fired, people can effectively damage inspection program. The application of oil, people strictly control the particle size of coal and dolomite. Should strictly control the particle size of bed material. Should be addressed furnace waste. To be able to solve the waste furnace after discharge. Natural gas boiler should be installed in areas where the application of calories, easy to install. Heating pipe can not be too long. It should have a good cable jacket. Water piping for an output from moderate to tail skew. Water resources to be equipped with a pressure regulating valve. As sewage gas, natural gas boiler chimney should widen to the outside, a heating furnace entrance width 1.5 to 2M. If you want to reduce the harm to the water wall tube can be appropriately regulate air pressure and wind speed and reasonable to reduce damage to the water wall. Inspection time is generally standby shutdown or shutdown condition. To check top head comprising the furnace wall is damaged, leakage of the furnace airtight and smoke. In the damaged condition requires immediate repair and welding, in order to ensure that no problem in the operation of steam boilers. Typically, before the ignition of gas-fired, fossil fuels must be added the charge in the combustion chamber, fossil energy and raw material-circulating bed material and gas in the wind, the strength and intensity of the flow down completely integrated. Bottom wind equipment, up for the core area. Exercise our powers in a ring outside the region along the furnace wall water swimming down, thus increasing the waiting time of coal particles in the furnace. Mineral particles, many of the ash and soot particles with a lot of fly ash, this resulting in rapid deterioration of the waterwall tubes continuously, so that damage to the wall thickness becomes soft, resulting in damage.
Industrial boilers and heating boilers What is the difference? Industrial boiler product in two ways, one steam used to generate electricity or gas, such as steam vaporized available fertilizer plant, coal as raw material, synthetic fertilizers, which is typical of industrial boilers, coal-fired industrial boilers still account for a large most gas is generally waste heat boiler for recovering waste heat. Industrial boilers commonly circulating fluidized bed boiler industrial boiler thermal power equipment is important, our country is today the world's largest production and use of boilers country. China's manufacturing industry is established and developed after the founding of New China. The term "industrial boiler" in the late 1930s, with the boiler thermal power generating units with capacity increasing, in order to distinguish high-capacity power plant boiler gradually adopted. Modern large-scale industrial boilers evaporation capacity has reached 100 to 200 tons / hour. Industrial boiler structure type in the structure can be divided into fire cartridge type, water and fire tube type 3 class. ① fire tube boilers; it is an early boilers, fire tube containing only water in the boiler twelve heating pot shell fire cylinder combustion means. Low thermal efficiency, large volume and steel consumption, since substantially no production 60s. ② fire tube boiler: it is in the vertical or horizontal potshell in addition to the fire tube, a plurality of means further smoke tube. The fuel in the combustion chamber high temperature flue gas produced after combustion smoke flows through these pipes heating pot of water, and then discharged into the chimney. Compared with fire tube boiler, since it is the number of multi-smoke tube, heated area increases, the exhaust gas temperature is low, high thermal efficiency, and the consumption of steel are relatively small volume of the boiler. FIG. 1 is a horizontal tempering tube boiler. When evaporation fire tube boiler is generally not more than 15 t /, working pressure not greater than 1.6 MPa, the thermal efficiency of coal is generally about 70%, of all oil-fired boiler automatic operation, the thermal efficiency can reach 85%. ③ water tube boilers: mostly used for larger capacity, higher pressure industrial boilers. Water tube boiler has a natural circulation type and DC two. Natural circulation water tube boiler with a single drum and double drum and other structures. Figure 2 is a double drum water tube boiler. Such boilers generally disposed in the convection tube economizer, an air preheater and sometimes, in order to reduce exhaust gas temperature. When coal efficiency up to 80% higher when the fuel. No drum DC industrial boilers, and the tubing coiled behind the inner wall of the furnace tubes of the convection heating surface composition. From the end of the tube into the water supply, the steam output from the other end. Industrial boilers small current, typically with separator and automatic control devices. The fuel and fuel combustion equipment is widely used in variety of industrial boilers, coal (bituminous coal, anthracite, lignite and coal waste, etc.), oil (heavy oil, residual oil and diesel, etc.), gas (natural gas or various industrial by-product gas) plant and urban waste (wood, bagasse, black liquor and waste, etc.) and so on. Therefore, industrial boiler combustion equipment is also varied. There layer belongs chain grate combustion apparatus, the feed grate, reciprocating grate, vibrating grate, chain grate stoker plus the like (see grate). Also useful way of fluidized bed combustion (see boiling furnace). In the evaporation of 65 t / h coal-fired industrial or larger capacity boilers generally use coal. Heating boilers boiler belongs to the category of civilian life, as people's safety awareness, and after 2000 are based on building heating hot water as heat medium, it does not allow the use of steam boilers, so in general we are talking about heating boilers often refers to pressure 4 ton coal pellet hot water boiler. There are many types of heating boilers, their classification is mainly divided in accordance with the fuel type, fuel heating boilers can be divided according to the different electric heating boiler, oil heating boiler, gas heating boilers, coal-fired heating boilers, biomass heating boilers. Which includes fuel: diesel, kerosene and heavy oil; which includes gas: Natural gas, LPG, city gas and biogas.
Procurement pressure 4 ton coal pellet hot water boiler should be noted that cold day which, as long as the use of pressure hot water boiler can feel as warm spring, enjoy the convenience of hot water. Extra large hot water boiler quality of life greatly improved. Pressure hot water boiler easy to use, but at the time of purchase the user must also confused how to buy, so the need to pay attention to what needs to select pressure hot water boiler For detailed understanding of. 1, when determining the use of boiler pressure hot water boiler purchase, you should consider using a different environmental requirements. If the client needs heating, you should choose a dedicated pressure hot water boiler is heated by circulating hot water in the hot water pump recycling. Back to the radiator, i.e. a heat sink, to deliver heat to every corner; hot water only, select a particular hot water, hot water circulating through the pump, hot water tank of hot water circulating in the hot water supply; number of users need to have two choices, so they have to choose to increase the heat exchanger in the piping system, so using two atmospheric pressure hot water boiler. 2, the heating area is determined, the amount of water by the calculation cycle, the required amount of hot water, boiler design used to determine the heating area or field. Accurate and scientific calculation and design can meet the requirements, without wasting resources. 3, to determine the fuel, boiler pressure hot water boiler style, coal or natural gas hot water boiler in three common, the boiler is electricity, gas hot water boiler coal or natural gas as an energy source. When selected, you can choose your own needs or favorable conditions. As long as meet the requirements of the boiler room, the style of choice should be simple and suitable for horizontal or vertical.
Since Prime Minister Li Keqiang in the "five" proposed "Blue Sky Wars," after the strategic plan states that China provinces and cities are doing to improve environmental protection. Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program," coal-fired units will conduct a comprehensive reform.
Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program" (hereinafter referred to as the "Program") said that before the end of 2018, the province's 300,000 kilowatts or more coal-fired units completed ultra-low emissions transformation. Continue to promote the 200,000 kilowatts class ultra low emission coal-fired unit renovation project, before the end of 2019, ultra-low emissions and strive to transform the province's total unit capacity of thermal power capacity of more than 75%.
"Program" also proposed to complete the transformation of ultra-low emission electricity generation units appropriate to increase the number of hours. Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. Coal-fired generating units to increase the technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal heating boiler pipe network coverage and the range of loose coal. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume. Before the end of 2020, within a 15 km radius of 300,000 kilowatts of heating and cogeneration power plant above range, in the case of cogeneration heating load to meet the heating needs, in addition to the need to retain the peaking boiler, coal-fired heating boilers and small coal-fired thermoelectric behind all closed down integration.
In addition, long-term control of total coal consumption in accordance with planning requirements, Jilin Province, to continue to reduce the amount of coal consumption, coal consumption in new coal projects to implement alternative reduction, by 2020, reduce the proportion of coal accounting for the province's total primary energy consumption to 63% the following. According to focus on the use of coal and clean use of principles, focusing on reduction of non-power coal, increase the proportion of electricity from coal, the state-assigned task is completed, the province's electricity by 2020, the proportion of thermal coal coal consumption reached more than 55%.
In the future, the province will carry out a comprehensive environmental aspects of governance, economic development and environmental protection go hand in hand.
