Coal fired water tube boiler is provided with a water-tube heating surface outside the drum, the high-temperature flue gas flows outside the tube and releases heat, and the water absorbs heat inside the tube. Because the cross section of the tube is smaller than that of the tube, the flow rate of soda water is greatly increased, and the steam generated on the heating surface is immediately washed away, which improves the heat absorption rate of the pot water. Water tube boiler application is widely, the drum diameter is small, the working pressure is high, the pot water capacity is small.
This series of boilers have good water circulation, high evaporation efficiency, good performance to adapt to load changes, and high thermal efficiency. Therefore, the boiler with higher pressure and higher evaporation capacity is water tube boiler. So-called water-tube boiler, it is water, steam or soda mixture flows in the tube, and the flame or flue gas in the tube combustion and flow boiler. SZL series coal fired boilers absorb the characteristics of quick loading boilers: the upper and the lower parts are used, the upper part is composed of the boiler body, the upper part is composed of the furnace wall and the insulation layer, the lower part is composed of the chain grate and the coal bucket, the installation is convenient, the cycle is short, the cost is less.
The boiler product has the advantages of compact structure, small occupation area, beautiful appearance, single layer boiler room layout and less civil engineering investment. Water tube boiler application is widely, easy to operate, stable operation, fast temperature rise and pressure increase, sufficient output, and widely adapted to coal. Complete auxiliary machinery, drum, induced draft fan, water pump, dust collector, etc. can meet the requirements of the boiler, wide adjustment range, convenient speed regulation.
Coal fired boilers realize the water supply, coal, grate operation, drum, air diversion automatic control, overpressure (steam boiler), overtemperature (hot water boiler), high, low water level (steam boiler), water supply, grate operation, drum, air diversion operation chain protection, to ensure the safe operation of the boiler. The boiler air supply adopts double side air supply device of storehouse type, each air chamber can be adjusted independently, with small air leakage and strong adjustable ability, so as to avoid the phenomenon of cross air and partial burning caused by uneven air distribution under the grate. It can well meet the requirements of combustion characteristics of chain grate.
Water tube boiler application in many places, using high strength large grate, avoid grate fracture phenomenon, and reduce the loss of coal leakage. The short and high front arch and low and long back arch are adopted to ensure the stable combustion of coal. At the same time, corresponding furnace arches can be designed according to different kinds of coal to meet the needs of combustion.
