Details Introduction about Coal Fired Circulated Fluidized Bed Boiler

ZBG has achieved an internationally cutting-edge level in terms of circulating fluidized bed boiler on technical platforms and standards. Existing circulating fluidized bed boiler products of ZBG include 6-280 t/h CFB steam boilers and 14-174 MW for CFB hot water boilers.

The features of coal fired CFB boiler

(1)burning efficiency reaches 95-99%.high burning rate,heat efficiency above 87%.energy saving,high efficiency.

(2)High flexibility of fuel,which can satisfy the burning of many kinds of fuels.

(3)Limestone can be added in bed material.during burning process reacts with SO2 of flue formulates sulphate,desulphuration can satisfy environment protection.reasonable air distribution and low temperature of furnace,which can control formulation of NOx and really reach environment protection.big adjusting range load can be adjusted rang 110%-30%.

(4)High automatic control,makes boilers running safely and economically in long tern.

(5)Adopt upper-exhaust high temperature cyclone separated device.high collection of bed material.high heat transfer coefficient,high ability of overload.

As a leading supplier of cfb boilers, we have demonstrated our ability to design once-through boilers, select proven materials and manufacture the pressure parts.

ZBG has entered the CFB market in the 1970s, demonstrating our ability to burn a wide variety of fuel while showing top class reliability with over 140 references.

Core improvements

The technology’s higher steam temperature and pressure parameters provide the most economical solution to improving plant efficiency and operating flexibility, achieving fuel cost savings and reducing emissions for each kWh of electricity generated.

Added value for our customer

Using our modular approach, we are able to modulate the power output to meet our customers needs, while ensuring high reliability and outstanding fuel flexibility. Using this same platform, we can provide a product delivering higher capacity when burning hard coal.
