Pinto and colleagues recommended that a temperature range of 850 to 900 C should be used for cogasification of coal and pine The temperature profile inside the directly heated cogasification reactor is also influenced by the proportion of biomass in the coal-biomass mixtures High pressure steam is expanded in turbine moisture content of exhaust steam increases which creates problem at exit end blades So reheat type turbine is most commonly used for large capacity turbine using high pressure steam Steam after expand
2019/6/6Net Heat Rate = (total fuel input to the boiler – the fuel that would required to generate the steam to process assuming the same boiler efficiency/steam turbine electric output (kW) Heat or power ratio is also an important factor in this discussion and it can be calculated by the formula• Coal Properties Affecting Combustion • Fuel Ratio (Fixed Carbon / Volatile Matter) is commonly used to evaluate the combustibility of coals • More advanced analysis rely on macarel analysis and vitrinite reflectance for evaluating combustion performance • • •
2020/9/14Coal is currently a major source of fuel for power generation industrial heat and on a smaller scale manufacture of coke and by-product coal tar In the mid to long-term anticipated increases in the cost of natural gas and petroleum relative to coal are expected to increase the incentive for
