Internal recirculation Coal Fuel CFBC Boiler Design

Summary:ZG unique internal recirculation coal fuel circulating fluidized bed CFBC boiler is a simplified, cost-effective and efficient boiler design.


ZG unique internal recirculation coal fuel circulating fluidized bed CFBC boiler is a simplified, cost-effective and efficient boiler design.

ZG internal recirculation coal fuel CFBC boiler design employs a patented two-stage particle separation system to provide high-solids loading and a uniform furnace temperature prfile.The benefits of this technology include superior combustion efficiency,low emissions,low maintenance,low pressure drop,and low turndown, resulting in improved overall plant performance.

Internal recirculation coal fuel CFBC Boiler Design features

Top supported, one- or two-drum designs; uses normally difficult to burn fuels in a circulating bed of inert particles to control the combustion process and gaseous emissions such as NOx and SO2; solids-laden flue gas exits the furnace to the U-beam particle separator where approximately 97% of solids are collected and internally recirculated to the furnace;an additional 3% of solids are collected at and recycled from a multi-cyclone dust collector.

ZG coal fuel CFBC boiler benefits include:

1.High combustion efficiency
2.A compact and economical design
3.High reliability and availability
4.Low maintenance costs
5.Reduced erosion
6.CFBC boiler Fuel flexibility design
7.Low emissions

Coal fuel CFBC boiler bed material specification

To start with the bed material is sand. Some portion is lost in the ash during the operation and this has to be made-up. In coal fired boilers the ash from the coal itself will be the makeup material.When firing bio fuels with very low ash content sand will be the makeup bed material. For high Sulphur coals Limestone addition to the bed material reduces SO2 emissions.

Coal fuel size in CFBC boiler

CFBC uses crushed coal of 3 to 6 mm size.This requires only a crusher not a pulverizer.From storage hoppers Conveyer and feeders transport the coal to feed chutes in the furnace. Start up is by oil burners in the furnace.Ash spouts in the furnace remove the ash from the bottom of the furnace.

Internal recirculation CFBC boiler fuels

High sulfur and high ash fuels and various waste fuels (petroleum coke, waste coal, sludge and oil pitches), wood,biomass,gob,and culm.

Biomass CFB Boiler Plant in Bahamas

In Bahamas, the biomass can be burned using conventional combustion technology like grate furnace or fluidized bed boilers. For power generation the biomass would be charged to the furnace of a steam boiler.Steam produces by the boiler will then drive a steam turbine generator to generate electricity. The typical capacity range for biomass power plants 1-20MW.
