product description The basic structure of the coal-fired boiler is made up of the upper drum, the lower drum, the water wall, the convection tube bundle, the economizer, the air preheater and so on. The front part of the boiler is composed of a water-cooled wall, and the water-cooled arch is formed by the front and rear water-cooled walls. The convective tube bundle is arranged between the upper and lower drums, the tube bundle is provided with lateral partitions to flush the flue gas, and the boiler is arranged with the economizer Preheater. The boiler grate with double or single-layer layout of the structure, better meet the actual needs of users. The sootblower interface is reserved for the boiler convection tube bundle and the economizer surface of the economizer, and the necessary means (especially strong cohesive) may take the necessary means. Combustion equipment using scaly chain grate, sub-chamber ventilation structure, sensitive adjustment. Combustion system is stable, coal adaptability, coupled with its own cyclone dust function, so that the boiler smoke black and the original dust concentration are in line with environmental requirements. Performance advantage Inverted "α" type furnace arch technology: The use of "Xi'an Jiaotong University National Science and Technology Progress Award" inverted "α" furnace arch technology, the front arch high and short, low and long arch, an increase of flue gas in the furnace burning time, improve the combustion efficiency; The rear arch can throw the unburned carbon particles from the rear of the grate to the front, making the coal more easily ignited, the flames are neat; the coal is of wide applicability. Unique secondary air structure: Effectively improve the furnace aerodynamic field, the hot particles lead to the front arch, is conducive to fuel ignition ignition, but also to extend the fuel in the furnace residence time, improve the fuel adaptability and utilization. Scaled grate structure: It has the advantages of no leakage of coal, uniform ventilation, automatic cleaning and easy disassembly. It can effectively reduce the exhaust air leakage and make the grate stable and reliable operation, which greatly improves the combustion efficiency.
