The coal fired industry used steam boiler coal fired consists of two large boiler drum out of factory , up major possession including boiler body , upper steel frame and furnace wall ,lower bulk including coal bucket ,chain grate ,lower furnace wall, and internal ventilation tube. Fuel: Bituminous Coal, dry-burning coal, hard coal, ligneous coal, etc.
1.Combustion and both sides of the furnace chamber adopt membrane water-cooling wall structure. With this kind of structure, the boiler has a high heat transmission coefficient, low heat loss, good air tightness, no distortion for furnace wall and no ash leakage.
2.Furnace front and rear water wall tube extend down to the upper portion of the grate and form the front and back arch, which extends the span of arch.
3. Inverted “α” arch furnace technology makes the front arch high and short, rear arch low and long. This structure increases the burning time of the flue gas in the furnace so as to improve the combustion efficiency. Besides, the streamline shape of back arch can throw the left carbon grains from the back furnace grate into the front so that the coal is easier to get ignited. Finally, many types of coal can be applied in the boiler.
4.The length of the front and back shaft is longer than the other domestic ones, which prolongs the time of fuel combustion in the furnace and lower the carbon content in the furnace slag. Thus, the overload ability of the boiler is strengthened with the increased effect area of furnace grate.
Vertical industry used steam boiler coal fired introduce vertical steam boiler Products: vertical steam boiler, all kinds of domestic furnaces comprehensive technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product has been designed applied for the patent, the boiler head boiler shell, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney. Performance: the boiler furnace grate rests within an upper portion of the U-shaped scraps, the direct flame furnace, and flushing mounted within curved tube furnace; vertical bent tube boiler structural features are: furnace interior curved inner pipe, increase radiation heating area. However, due to large water-cooling degree furnace, the furnace temperature reduced accordingly, therefore, generally suitable for burning high quality coal. The increase in the furnace masonry bricks, to maintain a high temperature furnace burn less coal. Better water circulation, where the site has been washed flue gas cooling water, the whole structure, good elasticity. Features: use of double grate combustion section of the combustion chamber, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust effect. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal.
Food factory industry used steam boiler coal fired should be noted that the ignition of the details need to pay attention when the details of the food factory steam boiler steam boiler ignition 1. food plant should be checked (including related accessories, Management) in front of a fire, and water supply. Before entering the water, the drain valve must be closed. Open air valve can discharge the boiler. 2, the treated water is slowly injected into the furnace, the inlet temperature is generally not higher than the boiler 40. When the water level rises to the minimum level of the water table, the water supply valve is closed, the stabilized boiler water level, the water level drops. With particular emphasis before the fire, you should check carefully the coal port and checkpoints in order to improve compliance with strict sealing conditions. Otherwise, it should clear the debris-side sealing surface, and a good gasket insertion, to ensure that meet strict sealing purposes. Since this is a forced air burner, during operation, gas leakage is not allowed, in order to avoid accidents. 3. When food factory fire steam boilers, open the bottom stoker grate and placed on the wood. After all the checkpoints closed, ignite the lighter. After strong fuel combustion, coal began to increase. When coal burning strong, continue to increase coal, closed after a stoker, hermetically sealed, turn the blower, so that coal continues to burn. burn. Strengthen the observation of the fire, the combustion gradually to normal.
