The coal fired steam boiler is a single boiler tube boiler shell boiler with movable grate and chain grate. Coal fired boiler performance is a horizontal – type three – return water – fire tube hybrid boiler, in the pot is arranged in a bunch of threaded smoke pipe. The radiation heating surface is the left and right water cooling walls of the furnace and the convection heating surface is the two wings of the furnace. The boiler body adopts the form of upper pot barrel, water wall tube and set box in the overall structure.
The industrial coal fired steam boiler is made of tube and front and back tubesheets. Zozen Boilers inside decorate a block fire wall, high combustion efficiency. It adopts light chain grate to realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, and equipped with scraper type slag discharge machine to realize automatic slag discharge. The front and rear arches of the furnace adopt new energy saving technology.
The coal fired boiler performance is superior. During combustion, the fuel falls on the grate from the coal sill and enters the furnace chamber for combustion. After the flame passes through the rear arch refraction upward through the combustion Chambers on both sides of the body, it turns to the front smoke box. Then the front smoke box is retraced back to the tube bundle in the pot, and then it enters the economizer through the rear smoke box, and is then pumped by the induced draft fan through the flue to the chimney and discharged to the atmosphere.
This series of coal fired boilers adopts arched tube plate and threaded smoke pipe to form the pot barrel, which makes the pot barrel change from a quasi-rigid body to a quasi-elastic body, and the smoke pipe change from a two-return journey to a single-return journey, thus solving the problem of tube plate crack. The threaded smoke pipe is used to enhance the heat transfer effect and improve the thermal efficiency of the boiler. It has the characteristics of stable operation, convenient adjustment, full output, quick pressure boost, environmental protection, energy saving and high thermal efficiency.
This series of industrial boilers adopt arched tube plate, two-wing flue, threaded pipe, etc., which solve the problems of boiler shell type, such as tube plate crack, lower drum bulge, water wall explosion, low thermal efficiency, insufficient output, poor coal quality and so on. The boiler itself has the effect of dust removal, so that the smoke emission of the boiler can meet the national environmental protection regulations.
Coal fired boiler performance have excellent, high thermal efficiency, fast steam production, long service life and other advantages. At the same time, PLC controller can be used to complete the closed loop control of temperature, pressure, flow and other analog quantities. Zozen Boilers specializing in the production of various types of boiler, high degree of automation, fuel burning full, burning effect is good, operation is stable and reliable, ensure the safe operation.
