Product introduction:
DZL series coal-fired horizontal three-return water and fire tube chain grate boiler is a fast loading boiler, safe and efficient, and the thermal efficiency can reach 82%. The boiler body is arranged longitudinally in a single cylinder, the threaded pyrotechnics tube is arranged in the cylinder to form a convection heating surface, the boiler cylinder and the water cooling wall on both sides to form a radiant heating surface of the furnace, and the combustion equipment adopts light chain grate. It has the characteristics of wide coal adaptation, small footprint, convenient installation and high thermal efficiency.
product feature:
1, the use of efficient heat transfer element a threaded smoke pipe, with a reasonable flue gas flow rate, so that the boiler thermal efficiency is 6-8 percentage points higher than the national professional standard.
2, arch tube plate, threaded smoke pipe make the shell from quasi-rigid body to quasi-elastic body, with the airfoil flue, completely avoid the problem of traditional pyrotechnics boiler high-temperature tube plate cracking.
3, reasonable water circulation circuit and unique return water ejector device (hot water boiler), improve the rising pipe water speed, avoid the water wall explosion.
4. Inertial separation of smoke and dust in the furnace is adopted. With the help of high-efficiency multi-tube dust collector, the boiler dust concentration can meet the requirements of a class of areas.
5, a reasonable boiler structure does not need steel frame to support its own weight.
6, the use of energy-saving, strong radiation furnace arch, can ensure the stable combustion of fuel.
7, the use of high standards, high-quality auxiliary machinery, accessories and automatic control equipment to ensure the safe and stable operation of the boiler, while reducing the labor intensity of the fireman.
8. Compact structure. 1-20t/h (0.7-14MW) boilers can be arranged in a single layer.
