A computational fluid dynamics (CFD) model of a 200 MW multifuel tangentially fired boiler has been developed using Fluent 6 3 26 which is able to model the three-fuel combustion system of coal blast furnace gas (BFG) and coke oven gas (COG) with an eddy-dissipation model for simulating the gas-phase combustion A level of confidence in the current CFD model has been established by carrying

Methanol cook stoves

The technology can be applied in s institutions (e g schools) and industries where it is used for boiler heating Methanol is derived from natural gas and therefore still results in emissions of CO 2 whereas the biomass gasification stoves convert biomass into a mixture of nitrogen carbon monoxide hydrogen and methane which can be burnt for cooking An important advantage of
