chain grate fire tube coal fired steam boiler

Henan combustion control and adjust fast boiler boiler company to introduce small series with the boiler combustion control and adjustment. 1 chain grate fire tube coal fired steam boiler combustion process is the basis of all the work process of the boiler, from the safe operation of the economy, environmental protection point of view, how to properly regulate the burning furnace, saving coal consumption is the responsibility of each fireman. 2 hot water boiler combustion conditions primarily by uniformly supplying the fuel, and air distribution adjusting reasonable combustion equipment is achieved, the coordination of the three, to ensure stable combustion conditions, economy, safety. When coal and boiler load changes, will need to adjust the amount of coal feed and the amount of the wind, in order to obtain a normal combustion conditions. Indicator 3.1 normal combustion conditions 4.8.3 normal combustion means: timely fire burning strong, ash burnout. Specific requirements:. A fuel inlet from the anterior arch 0.1-0.15 m fire, gray ash ex chain at the 0.3-0.4 m burnout. B. fire bed smooth, dense and uniform flame, without flame or blown partial blackening phenomenon. C. Flame intermediate white light, two dark, the fire grate bed length representing more than 3/4 of the effective length. D. pale gray smoke or nearly colorless. In order to achieve good combustion conditions, must maintain a high furnace temperature, the temperature of the upper layer is generally burner combustion layer preferably 1100-1300 deg.] C, may be determined according to the color of the flame. Furnace temperature and flame color relationship in the following table. The outlet temperature of the furnace can also be used to determine, 29MW boiler design furnace outlet temperature of 1017 ℃, 58MW of 998 ℃. 3.3 In the case of normal combustion, the oxygen content in the flue gas is constant, the oximeter, fireman can understand the situation of excess air in the furnace, the furnace excess air is generally mechanical 1.2-1.4%, of excess air and oxygen table below. Ash 3.4 combustibles content is an important sign of good and bad conditions of the boiler combustion, which fuel, combustion equipment, and operations are closely linked, general mechanical furnace ash carbon content should be less than 10%. 3.5 water boiler operation should ensure that in the case of no condensation of the tail to minimize exhaust gas temperature, exhaust gas temperature is controlled at 110-160 ℃. Adjusting and controlling the amount of coal to a fireman who adapt to changes in load, the supply must be based on different types of coal and the various stages of the heating season, the weather trend, the thickness of the seam is determined, the general control of the thickness of 80-100mm low load, medium load control in 100-120mm, high load control in 120-160mm. 2 fireman in specifying a seam thickness, to be due to the furnace, because coal should comprehensive analysis, on balance, for the ash content, water large, large particles, high ash melting point of the coal, generally the appropriate tone thick seam, opposite seam is to tune thin. Small particles of coal or pulverized coal and a low ash melting point of the plurality coal i.e. strong bonding to a thin coal seam. Generally the 3 or the boiler when the load change is not too large, the method should not be used to adjust the thickness of the seam. Because coal seam thickness adjustment can not be effective immediately adjust the load only when a large load changes, and long-term stable operation of the boiler in the new load considering regulating coal seam thickness. 4 seam thickness can be achieved by adjusting the height of the coal and layered coal hopper shutter speed of the drum. Shutter elevation coal, coal may be added into the same hierarchical improved coal hopper drum speed may be increased into the amount of coal seam in order to obtain a proper height, the height of the shutter must coal, coal hopper drum speed stratified and chain speed adjustment of the three.

Fangkuai Boiler is a clean-up boiler equipment based on various excellent scientific and technological advancements, focusing on product development, manufacturing, and manufacturing that are more efficient, environmentally friendly, and energy saving, and meet the basic national conditions of environmental protection in China. In order to promote the rapid development of the heating furnace manufacturing industry, people-oriented, consider the specific requirements of customers in the manufacturing industry for heating furnaces in various industries.

How to improve the energy efficiency of industrial boilers, industrial boilers how to improve energy efficiency 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.

On a more specific type of a gas boiler chain grate fire tube coal fired steam boiler steam boiler and comparison of gas steam boiler and steam boiler, the following will be involved, for this specific kind of gas steam boiler furnace. Moreover, since it has a wide range of applications, and is the product website and keywords, so it is necessary to conduct in-depth and comprehensive understanding, so as to not miss any of its knowledge, and at the same time, but also allows the product to have good results, let us benefit from it. 1. Gas steam boiler and steam boilers, whether they comparable? Gas steam boiler and steam boilers, which are two specific types of boilers, however, from a professional point of view, these are two completely different boilers, although all in the boiler in this category. Therefore, gas steam boiler and steam boilers are not comparable, not suitable for comparison, because then no significance and value comparison. 2. The high-temperature gas-steam steam oven gas used, what to choose should be based on? High-temperature gas-steam oven gas and steam is used, it should be selected based on grades and hot gas-steam process requirements, and that should be the right choice for a variety of high-temperature gas-steam grades and strictly comply with the requirements "organic heat carrier furnace technology to monitor the safety regulations" this standard in order to achieve the proper use of gas steam. 3. gas steam heater and gas steam boiler, Is there a difference? Gas steam heater and gas steam boiler, although the two are similar in name photogenic, however, are two different things. Because, gas steam heater is a resistance heating gas with steam, and the steam boiler is the use of gas fuels, such as coal and natural gas to provide heat these. In addition, they use in the oil, but also very different.
