Chain Grate Coal Fired Boiler Introduction

Coal fired boilers used to be the most core energy and power equipment during the industrial revolution. With the development of the industrial Revolution, the early technology has been constantly improved. In the past 100 years, a variety of furnace types, mainly chain grate boilers, have been gradually formed. Coal-fired industrial boilers are widely used in the market and still play a very important role. Due to the restrictions of natural gas resources, price and gas supply area, it is impossible for gas-fired boilers to completely replace the chain grate coal fired boiler, and coal-fired boilers will play an important role for a long time.

DHL series chain grate boiler is to the company in product and technology import and domestic outside tube boiler, on the basis of technical research, according to the technical development of coal for chain grate characteristics and the market demand for its innovative design of water cycle and reliable and efficient combustion of large capacity, low pollution chain grate boiler energy-saving products.

SHL double drum exhaust type chain grate coal-fired boiler is Zozen Boilers with xi ‘an jiaotong university the latest achievements and latest development in boiler combustion theory technology and the development of the fourth generation of chain grate boiler. The boiler has many advantages, such as full output, high thermal efficiency, stable and reliable operation, strong overload capacity, wide fuel applicability, energy conservation and environmental protection.

SZL chain grate coal fired boiler skillfully applies the water-cooling arch technology and membrane water-cooling wall technology of large chain furnace combustion system to the assembly boiler, and the technical indexes are in the leading level. With high efficiency, strong overload capacity and wide adaptability of coal, the boiler is praised as the best design scheme of similar products and has advanced level in the world.

Chain Grate Coal Fired Boiler Application

This series of industrial boilers can be used in industrial and mining enterprises, central heating and heating fields, and can also be used as peak heat power plant boilers to regulate the operation of urban heat network. At the same time, 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.

Chain Grate Coal Fired Boiler Advantages

  • The internal circulation vulcanization and reignition device of fly ash based on high temperature separation is adopted. Design method of composite velocity of convective heating surface of Angle tube boiler. Furnace arch technology, improve fuel combustion characteristics, wide applicability of coal.
  • Special slag removal technology is adopted. It can effectively reduce the air leakage of the grate, make the grate operation stable and reliable, and greatly improve the combustion efficiency.
  • Special secondary air structure is adopted. It can effectively improve the aerodynamic field in the furnace and lead the hot particles forward to the arch, which is beneficial to the ignition and ignition of fuel, at the same time, it can also extend the residence time of fuel in the furnace and improve the adaptability and utilization rate of fuel.
  • Membrane water wall structure is adopted on both sides of furnace and burnout chamber of coal-fired boiler. The membrane water-wall structure is the original design of our company. The membrane water-wall structure used for power station boilers is applied to assembly boilers. Its advantages include large heat transfer coefficient, good conduction effect, low heat loss, good air tightness, no deformation of furnace wall and no ash leakage.
  • The combustion time of fuel in the furnace is prolonged, the combustion time of coal is full, and the carbon content of slag is reduced. The effective area of the grate is increased and the overload capacity of the boiler is obviously enhanced.
  • After delivery, install valve instrument, drum, induced draft fan, smoke air pipe, economizer, dust remover, slag extractor.
