Introduction

SHX CFB boiler: evaporation capacity 10-75l, with steam pressure of 1.25-2.5MPA and the steam temperature is saturated steam and superheated steam. hot-water boiler 7-58mw, supplies 130C/150’c hot wat. Under pressure of 1.0-16MPA: the returning water temperature is 70C/90C CFBC tech nology, boing a new type and matured high efficient, low pollution green technology, has a lot of merits, which can not be found in other combustion method.

Currently, requirements for environment protection become stricter daily, and electricity load adjustment range for power plant becomes bigger, varieties of coal supply changeable. direct combustion of raw coal takes higher ratio, national economy develops unevenly in different level, the contradiction between environment protection and coal burning pops out daily more, CFB boiler has become a first choice for high efficiency and low pollution new combustion technology.

Large furnace design

  • Large furnace,lower flow speed design. Allow pipe technology decrease erosive wear
  • Extend the stay time of coal particles in furnace to make coal fired sufficiently

Air preheater

  • Steel tube type air preheater decreases the exhausted gas temperature,improve furnace inlet air temperature and boiler heat efficiency

Ignition method

  • Unique wind chamber design provides two methods for user:ignition on bed and ignition under bed
Performance advantages
  1. CFB belongs to low temperature combustion; therefore, the exhaustion of nitrogen oxide is far more fewer than from coal powder furnace, only 200ppm approximately; at the same time. It is feasible to actualize direct desulfurizing during combustion, The efficiency of desulfurization is high and the equipment is simple and cheap as well. The initial investment for desulfurization and performance cost is a far lower than that of (PC+FCD)
  2. Extensive fuel ad apta bility and high combustion efficient, especially suitable for low orie inferior coal.
  3. The exhausted cinder has better activeness,liable to actualize intrgrated utilization and free from pollution.
  4. 4.Wide range for road adjustment, low load may lower to 30% approximately of the rated load.
