SZL Series Steam Boiler Introduction

  • DZL series quick-load boiler is a horizontal three-return water and fire pipe chain grate boiler.
  • The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.
  • Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.
  • The boiler body is arranged in a longitudinal direction of a single drum, and a threaded pyrotechnic tube is arranged in the drum to form a convection heating surface, and the drum and the water wall on both sides constitute a furnace heating surface.
  • According to different capacity, different numbers of independent air bins are arranged from front to back of the grate.
  • The user can reasonably adjust the air distribution according to different combustion conditions to ensure that the fuel is fully burnt.
  • Secondary air is input to disturb fuel gas in the furnace, to ensure the fuel is burnt totally. The independent secondary fan makes it easy to control and adjust the air volume and air pressure.
  • The burning equipment adopts a light chain grate; the overall quick release form is delivered. Electrical control realizes stepless speed regulation of the grate, limit parameter alarm and interlock protection.

SZL Series Biomass Steam Boiler Feature

  1. The convective heating surface has high heat exchange efficiency and the boiler operation efficiency is stable.
  2. Chain grate panel, front and rear smoke box panel are all cut by CNC plasma cutting machine, neat and beautiful.
    Pot barrel volume is larger, the internal device is complete.
  3. This series of biomass fired boiler has functions of automatic feed water regulation, automatic alarm of high and low water level, automatic protection of overpressure, automatic protection of flameout, etc.
  4. SZL series steam boiler operates smoothly and has certain overload operation capacity.
  5. The front and rear arches match reasonably, the furnace arch coverage rate is large, the furnace temperature is high;
    Double drum layout, high combustion efficiency, operation cost saving 5-10%.
  6. The cross section ratio of each heating surface falling surface and rising pipe is reasonable, and the combustion condition is stable.
  7. The amount of air required by different fuel in different combustion stages of each air chamber can be adjusted artificially. The horizontal wind pressure is consistent, and partial burning will not occur.
