Read MoreThe boiling range is between 300°C and ~700°C. Due to its semi-fluid consistence, HFO has to be preheated to make it combustible in engines. As a residual product, HFO is a relatively inexpensive fuel – it typically costs 30% less than distillate fuels. ZBG can provide heavy fuel oil power plant boiler, capacity:20-130t/h.
Read MoreUsing typical boiler and steam turbine generating efficiencies, 100 MMBtu/hr heat input provides about 10 MW electric output. The two most commonly used types of boilers for biomass firing are stoker boilers and fluidized bed boilers. Either of these can be fueled entirely by biomass fuel or cofired with a combination of biomass and coal.
