DZL single drum horizontal chain grate coal fired boiler has compact structure, smaller overall dimension compared with the same type of boiler, and saves capital construction investment of boiler house. The heat transfer coefficient and heat efficiency of the boiler are improved by using the threaded flue gas tube to enhance the heat transfer. Due to the disturbance of flue gas in the pipe. It is not easy to accumulate ash in the smoke pipe, which plays the role of self cleaning. The unique double-layer secondary air design improves the ignition conditions of biomass fuel. The independent air chamber is adopted to achieve the reasonable air distribution, so that a combustion friendly aerodynamic field is formed in the furnace, making the combustion temperature high and the combustion efficiency high.

  • Previous:
  • Next:

  • 1. The medium temperature is low and the heat loss is small.

    2. Hot water heating is widely promoted with safe and stable operation in internationally.

    3. The secondary air is arranged in the front and rear arches to ensure the secondary combustion of fly ash after particle decomposition and high combustion efficiency.

    4. Adopt scale chain grate, mechanized feeding. It has the characteristics of uniform feeding, stable combustion, convenient control, uneasy tempering and convenient mechanical ash cleaning.
