coal fired smoke tube steam boiler

Do you know what it is gas energy saving boiler gas boiler energy-saving and environmental protection Many customers do not believe, how coal energy-saving environmental protection? Zheng Boiler Group today for everyone to analyze environmental history of the gas boiler. Energy saving gas boiler pot Zheng Group production of a new product, a gas coal fired smoke tube steam boiler. Energy saving gas boiler pot Zheng Group production of a new product, a gas steam boiler and gas hot water boiler, gas steam boiler models which are mainly DZL steam boiler gas chain, DHL chain gas steam boiler, SHL chain gas steam boiler SZL chain and energy-saving gas steam boiler and circulating fluidized bed boilers. Zheng pot boiler gas saving and environmental protection are "perfect green and environmentally friendly boiler boiler auxiliary boiler machine environmentally friendly application process installation service" model pioneered go on the road "environmental effects Enhancements". In addition to these types of environmental protection boiler, auxiliary equipment, environmental protection is also an important part of the environmental process. Energy saving boiler fuel gas separation efficiency as high as 97.97%, combustible low-quality coal, good desulfurization effect, can significantly reduce sulfur corrosion of equipment, in favor of low quality coal combustion, coal adaptability strong. Boiler fan low energy consumption, high economic efficiency, and can effectively avoid the fan big horse car phenomenon. To more than dust and coal in the coal auxiliary, not only an automatic cleaner, convenient safe, maintenance.

Measures to increase the gas coal fired smoke tube steam boiler economy which economy improving gas steam boiler can not only reduce operating costs, but also in line with the national energy saving policy requirements. Specifically refer to the following measures: 1, to improve equipment management level, efforts to reduce internal and external leakage thermal equipment and systems, reducing the working fluid and heat loss. 2, improve the economy auxiliary operation, to reduce the loss of auxiliary equipment, making it possible to run in the high zone. By testing to determine its associated auxiliary systems of reasonable conditions in the different operating modes of operation, efforts to reduce power consumption rate. 3, chemical strict supervision of the boiler operation, strict control of condensate water hardness, the amount of dissolved oxygen in the feedwater, boiler feed water and the PH value of water, steam quality, to prevent the boiler heating surface, condenser, heater, and corrosion of turbine flow section, fouling and salt accumulation caused by the deterioration of boiler equipment operating conditions. 5, to take measures to save water and power, such as to maintain a reasonable rate of circulating water is concentrated, and to improve the ratio of gray water recycling waste ash comprehensive utilization. 6, the main measures of force cycle efficiency is the main steam pressure, main steam temperature, reheat steam temperature is maintained at a predetermined value, back to normal investment in thermal efficiency, water temperature in the design value, efforts to reduce back pressure steam turbine and so on. 7, to improve the efficiency of the steam boiler, a steam boiler to reduce the exhaust gas temperature, air leakage rate boiler fly ash combustible content, good milling system to adjust combustion boiler test, develop various conditions of operation of the card, as the operator operating personnel in accordance with. Yaoan gauge 8, to strengthen the fuel management, strict measurement, strict control of coal into the plant, allowing coal from the design value is within the limit value, especially for volatile coal, ash, sulfur, strict supervision coking characteristics the boiler can run under good conditions. 9, strengthen metrology run, the boiler operation indicators to quantitative analysis, provide a reliable basis for the economic operation of the steam boiler. Zheng gas steam boiler pot consists of three parts: main boiler, chimney and piping system, wherein the host section has been completed and the chimney is manufactured in the factory, the host supporting the pipes and valves, the meter has been properly installed randomly transported to the host site and can be assembled chimney. Field gas supply is turned on, power supply, water line to test. Greatly reducing the installation cycle, and can ensure product quality.

The purchase of gas-fired boiler, we are more anxious shopping center, but for gas-fired boilers are not very understanding. After the introduction of others, we understand each other fast boiler more comprehensive, and more trust fast boiler. After the boiler put into use, it turns out, party fast products fully meet the needs of our shopping centers. --customer feedback

Details of operation of the boiler details chemical energy chemical energy Note 1 Note that operation of the boiler, fuel delivery is controlled with respect to the thickness of the layer of coal-fired boilers, the actual operation, the particles of different sizes on the same coal seam, unreasonable distribution, uneven ventilation, combustion is not uniform. The method can be employed uniformly stratified combustion to coal, to improve seam incomplete combustion: first administration of large particles of coal in the lower layer, the upper layer after administration minimal, large particle surface area of ​​small particles of coal, the need to burn a long time, this time is in the air the highest concentration of oxygen lower position; the other hand, small particles of coal on top, large surface area, a low oxygen concentration, full use of excess air. 2, the flow regulating damper excess air ratio is too large, a large loss of smoke; excess air ratio is too small, incomplete combustion loss is large, and therefore need to properly regulate the air flow to minimize loss of two or more. Usually in the flue gas analyzer backpass smoke, the control amount of wind of carbon monoxide is reduced to a reasonable value. For unconditional for gas analysis, empirical judgment by the naked eye can see the flame in the furnace, the flame pale described excess air amount; brown opaque flame, smoke black smoke indicates incomplete combustion. 3, there is a 1mm thick scale surface water quality management experiment boiler heating surface, waste of fuel from about 3% to 5%, in the presence of 3mm thick scale, waste of fuel of about 5% to 10% [3]. Water two general steps: pre-treatment, ion exchange or reverse osmosis. 4, cleaning blowdown gray scale or fouling deposition in the heating surface, increased heat resistance, reduced heat absorption wall, to improve the furnace exit gas temperature, boiler output decreased, but to increase the amount of cast coal, causing furnace exit gas temperature further improve a vicious circle. Therefore, timely cleaning clear dirt is particularly important. 5, the energy efficiency of the heat insulation testing industrial importance boiler showed small boiler in the case of good thermal heat radiation loss is about 3%, if the wrong selection insulation material, the thickness is too small, or even damage, does not include local heat, heat losses will be higher, the boiler has been running, has been caused by waste heat into the air. When the shutdown check whether the furnace wall insulation bricks off; isolated brick flue check is complete, to avoid shorting the flue gas; outer portion boiler, steam pipes and other insulation damage to be repaired; when heat insulation, low thermal conductivity of the material ( i.e., materials with good thermal insulating properties) on the inner layer having a better thermal insulation effect; respond to the economizer outer insulating layer for laying under conditions permitting. 6, to solve the problem of air leakage air leakage boiler boiler unit during operation is a common problem, the need to ensure the tightness of the boiler, furnace air leakage above all, do not close the site to check the furnace wall, door, inspection holes, etc., can be candles law, candles near these places, to observe whether the candle flame inward deflection to judge. Second leakage tail heating surface, the flue stack leakage mostly welding cracks, elbow bend, the expansion joints wear wear; mostly air superheater corrosion or wear leading to leakage through the pipe, the boiler shutdown should focus an examination.
