The coal fired chain grate boiler is a kind of horizontal three-return water and fire pipe mixed boiler. The chain grate boiler manufacturer is equipped with light pipe water cooling wall on the left and right sides of the furnace, and the light chain grate is used to achieve mechanical coal filling. Equipped with blower, induced draft fan for mechanical ventilation, and equipped with scraper slag machine to achieve automatic slag. The front and back arch of the furnace adopts new energy saving technology arch. After the fuel falls to the grate from the coal sash, and enters the furnace for combustion, the flame passes through the rear arch refraction upward through the burning embers on both sides of the body to the front smoke box, and then by the front smoke box back to the tube bundle in the pot, through the back smoke box into the economizer, and then by the induced draft fan extraction through the flue to the chimney exhaust to the atmosphere.
The operation of coal-fired boilers has been mechanized, reducing the labor intensity of stokers. The chain grate coal fired boiler adopts quick installation factory, to the use of the site, installed with the valve instrument, drum, induced draft fan, smoke wind pipe, economizer, dust collector, slag machine. The coal loading machine and the water and electricity road can run, and has the characteristics of fast starting fire. Convenient installation and movement can save a lot of infrastructure investment. The assembly of the chain grate boiler is divided into two parts (the upper body is the heating surface, the lower body is the combustion equipment), and the site is assembled. Assembly boiler is generally in the form of components factory, such as drum components, grate components, etc., after the site will be assembled and installed. The installation process is also more convenient and quick.
Chain grate boiler manufacturer produce coal-fired boilers which are carefully designed according to the needs of consumers and the advantages of similar products. This series of boilers have the advantages of fast installation, time and material saving, compact structure, small occupation area, high reliability, high thermal efficiency and strong overload capacity. The boiler adopts light chain grate with high degree of automation, equipped with dust removal equipment, less environmental pollution, has good comprehensive economic and technical indicators, and is well received by the majority of consumers.
The burning equipment of DZL series coal fired boiler is chain grate. The main engine of this series of boiler products is arranged with single cylinder longitudedly, and single return threaded smoke pipe is arranged in the cylinder. The left and right sides of the furnace are equipped with light pipe water cooling wall, and part of the rising pipe is pulled to the furnace to form the furnace top. The bottom of the drum is hung with refractory bricks, which do not receive radiation from the hot flame. There are two symmetrical convection flue at the bottom of both sides of the drum, and the water wall bend pipe is assembled at 750mm from the center line of the drum, which completely solves the disadvantages of tearing weld caused by heat expansion and cold contraction of the drum and the collecting box.
This series of coal-fired boilers are designed with push-pull gate ash removal device. The gate adopts heat-resistant cast iron finishing sealing structure, so as to effectively prevent secondary combustion deformation and grate air leakage. Chain grate boiler manufacturer through advanced production experience, boiler wing flue setting, so that the flue gas smoothly into the front smoke box. The temperature of the front tube plate is the same and lower than 600℃, and the tube plate crack caused by the temperature stress of the chain grate coal-fired boiler is avoided to the maximum extent.
