Coal-fired chain grate boiler is a kind of horizontal three-return water-fire tube mixed boiler, in which a bunch of threaded smoke tube is arranged in the drum. Coal fired boiler sales furnace left and right two sides of the water wall for radiation heating surface, furnace two wings for convection heating surface. In the overall structure, the coal fired boilers adopts the form of upper cylinder, water wall tube and collection box symmetrical arrangement. The boiler is made of welded tube body and front and rear tube plate. The boiler is equipped with a wall to prevent the fire, and the combustion efficiency is high.
This series of chain grate boiler can realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, and equipped with scraper type slag discharging machine to realize automatic slag discharging. The front and rear arches of the furnace adopt a new type of energy-saving technology. Fuel from the coal hopper fell on the grate, into the furnace after burning, the flame through the rear arch refraction upward through the body on both sides of the embers chamber fold to the front smoke box, and then from the front smoke box back to the pot tube bundle, through the smoke box into the economizer, and then by the induced draft fan pumping through the flue to the chimney exhaust to the atmosphere.
Coal fired boiler sales using the latest scientific and technological achievements, stable and reliable operation, worthy of user trust. Such as: arch tube plate, screw smoke pipe, solve the boiler shell type tube plate crack, water wall burst tube, low thermal efficiency, insufficient output, poor adaptability of coal quality and other problems. The arch pipe plate and screw pipe are used to form the cylinder, so that the cylinder is changed from a quasi-rigid body to a quasi-elastomer structure, and the pipe is changed from two return passes to a single return passes, thus solving the problem of crack in the tube plate. The effect of heat transfer was enhanced and the thermal efficiency of the boiler was improved by using screw pipe.
The series of coal fired boilers adopt arch tube plate, two flue flue and screw pipe, etc., which solve the problems such as tube plate crack, bottom bulge of tube barrel, tube burst by water cooling wall, low thermal efficiency, insufficient output and poor coal quality of boiler shell type boiler. Coal-fired chain grate boiler has the advantages of stable operation, convenient adjustment, sufficient output, fast pressure boost, environmental protection, energy saving and high thermal efficiency. The boiler itself has the function of dust removal, so that the smoke and dust emission of the boiler can reach the target of environmental protection regulations.
Coal fired boiler sales equipped with blower, induced draft fan for mechanical ventilation, and equipped with scraper type slag machine to achieve automatic slag. The boiler has high thermal efficiency, the operation is mechanized, and the labor intensity of the storer is reduced. The boiler uses quick assembly factory, to the use of the site, installed valve instrument, drum, induced draft fan, smoke duct, economizer, dust collector, slag machine. The coal feeder and water and electricity road can be operated, and has the characteristics of fast starting and ignition. Zozen Boilers specializes in producing high quality boiler products, has established friendly and cooperative relations with many customers, has established a complete set of boiler projects in more than 100 countries and regions, and has won the consistent praise and trust of customers.
