Project Cost Power Plant 10 MW CFB Boiler

Summary:Project Cost of 10 MW Circulating Fluidized Bed (CFB) plants can comply with environmental emissions regulations without flue gas treatments for sulphur capture and for NOx reduction. Because of the easier preparation of the fuel feed (crushed instead of finely ground), CFB is amenable to the use of lignite and co-firing with biomass.

Project Cost of 10 MW Circulating Fluidized Bed (CFB) plants can comply with environmental emissions regulations without flue gas treatments for sulphur capture and for NOx reduction. Because of the easier preparation of the fuel feed (crushed instead of finely ground), CFB is amenable to the use of lignite and co-firing with biomass.

The limiting factor for co-firing with biomass, in addition to the availability of sustainable biomass, is its high alkali content which reduces the softening temperature of the lignite ash and can cause increased fouling of boiler tube surfaces. However the combustion temperature in CFBC is sufficiently low to avoid slagging of heat exchangers. There are many 10MW size sub critical CFB units in operation, and there is now an offer of a 10 MW CFB boiler with supercritical steam on the market.

Coal drying is part of coal preparation and grinding for PC combustion and for crushing for CFB combustion. It is also integral to the thermodynamic design of the plant. Drying improves crushability or grindability of the coal and assists ignition and flame stability, and can also improve the plant efficiency.

For high moisture sub-bituminous coal or lignite, furnace gas withdrawn from the top of the boiler combustion chamber is used as drying agent. When the furnace gas is reintroduced into the boiler transporting the dried pulverized lignite and the vapour through the burners, the plant efficiency is unaffected. If, however, boiler exit flue gas is used for lignite drying and low pressure bleed steam from the steam turbine is used for feed water heating, the plant efficiency increases. Comparison of measurement data for the alternative systems of furnace gas and flue gas-drying of a lignite with 47% initial moisture dried to 25% shows 4.9% relative efficiency improvement for flue gas coal drying.

Further improvement of the plant efficiency can be gained by dewatering high moisture coals prior to combustion . The temperature of the vapour leaving a steam-fluidized coal dryer is raised by compression, and used for further drying by means of a tubular heat exchanger immersed in the coal dryer. Coal-moisture is removed in the form of liquid water; the boiler is fired by dried coal, and the water vapour content of the flue gas is reduced to the sum of the residual moisture of the dried coal and the combustion products of the hydrogen in the coal.

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.
