The coal fired steam boiler formed the furnace top heating surface by pulling part of the rising pipe on both sides of the header toward the chamber and then introducing the bottom of the boiler barrel and adding the heat insulation at the bottom of the boiler barrel. The industrial coal fired boiler structure has successfully solved the problem that the bottom of the pot tube is directly radiated by the high temperature flame, avoiding the defect of “bulge”. The installation of two-wing flue of coal-fired boiler makes the flue gas enter the front smoke box smoothly, so that the temperature of the previous tube plate is the same and the tube plate crack is avoided due to temperature stress.
The front and rear arches of this series of coal fired steam boilers are all supported by water wall pipes and formed by integral pouring structure. The arch design adopts the latest scientific research results, the rear arch is low and long, the exit section is anti-inclined, the front arch Angle is 45° and the back arch echo, forming an obvious inverted flame, which is conducive to the combustion of inferior coal, and the coal has strong adaptability. The design of the seal structure on the side of the grate is advanced and reasonable, avoiding the defects of the seal on the side of the grate which is damaged by the uneven air distribution on both sides of the grate.
Industrial coal fired boiler have the advantages of compact structure, small volume, large output, quick pressure boost and high thermal efficiency. 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. It is 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, wineries, pharmaceutical factories, packaging factories, building materials factories, coating factories, natatorium and other enterprises and institutions.
The overall structure of the coal fired steam boiler is composed of a furnace chamber and convection flue with water cooling walls arranged on both sides. The coal fired boilers barrel is arranged with a single-return thread smoke pipe and a cast iron economizer at the end. Adopt bulk chain grate to realize mechanical combustion. Mechanical ventilation with an induced draft fan, and a slag discharge machine to achieve mechanical slag discharge, complete control monitoring instruments. 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.
Industrial coal fired boiler have large heating area, long flue gas flow, good heat transfer effect and low exhaust temperature. So high thermal efficiency, low operating cost, more economical to use. This series of steam boilers have stable and full combustion, fire, heating and pressure boost. Equipped with a number of protection devices such as water level gauge, safety valve and pressure gauge, the operation state is clear at a glance, fundamentally the user’s worries, safe and reliable use. As the high-temperature flue gas first enters the settlement chamber, and then enters the two wings of flue gas and the front smoke box from both sides, the effect of smoke elimination and dust removal is good.
