The design and manufacture of coal fired steam boilers are strictly carried out in accordance with the standards. The furnace body is equipped with gauges, safety valves, water level gauges and other instruments. When the boiler reaches a certain pressure, the safety valve automatically opens, deflates and depressurizes, ensuring safe and reliable operation of the boiler. The overall structure of the boiler adopts the three-way water-fire tube structure with longitudinal arrangement of a single pot barrel, and both sides of the furnace are densely covered with light pipes and water-wall pipes, so the design structure is reasonable and compact. Industrial coal fired boiler heating area is large, the flue gas flow is long, the heat transfer effect is good, the exhaust temperature is low, so the thermal efficiency is high, the operation cost is low, the use is more economical.
Coal-fired boilers have the advantages of compact structure, small volume, large output, quick pressure boost and high thermal efficiency. This series of steam boiler also has the advantages of high reliability, high safety, strong overload capacity and high thermal efficiency, which is the best design product of similar products. The large boiler parts (mainly upper body and lower base) have been assembled in the plant. After the large boiler parts (mainly upper body and lower base) are in place, the user only needs to complete the interfaces, auxiliary machines and pipeline system to run.
Industrial coal fired boiler are widely used in schools, textile factories, clothing factories, printing and dyeing factories, restaurants, food factories, beverage factories, soybean products factories, meat products factories, canning plants, wine factories, pharmaceutical factories, packaging factories, building materials factories, coating factories, natatorium and other enterprises and institutions.
This series of industrial coal steam boilers have successfully solved the problem that the bottom of the boiler cylinder is directly radiated by high temperature flame and avoid the “bulging” defect by drawing part of the rising tube on both sides of the collector box to the furnace chamber and then introducing the bottom of the boiler cylinder and forming the furnace top heating surface with the heat insulation and casting at the bottom of the boiler cylinder. The two wings of the flue gas can enter the front smoke box smoothly, so that the front tube plate temperature is the same, avoid the tube plate crack caused by temperature stress. The seal structure design on the side of the grate is advanced and reasonable, with air inlet on both sides. A new type of adjustable arm screw is adopted to make the cross section ratio of adjustable air reach 100%. Flexible adjustment, uniform air distribution. The push-pull slug cleaning device is designed. The slug adopts heat resistant cast iron finishing sealing structure, which can effectively prevent secondary combustion deformation and exhaust air leakage.
Water-cooling walls are arranged on both sides of industrial coal fired boiler to form the furnace chamber and convection flue. There are single-return threaded smoke pipes in the boiler barrel and energy-saving devices at the end. The front arch and the back arch are water-cooled in the furnace. The front arch is stepped and the back arch is herb-shaped, which makes the coverage of the arch close to 85% and is conducive to the burning of bituminous coal. Mechanical combustion is realized by chain grate. Mechanical ventilation with an induced draft fan, and a slag discharge machine to achieve mechanical slag discharge, complete control monitoring instruments. Welcome to the majority of users to consult procurement boilers product, we will serve you wholeheartedly.
