Get A QuoteAbstract: The paper presents a mathematical model, results of calculations and energetic characteristic of biomass fired recirculating flue gas fluidized bed boiler. Methodology of calculation and mass and energy balances were worked out according to standards PN-EN 12953 - 15 and DIN 1942. In order to develop mass and energy balances, compositions of flue gas were used.
Get A QuoteThe traditional calculation method of industrial boiler thermal efficiency needs to input many parameters, which leads to a lot of complicated calculations. It is not suitable to make an accurate judgement on the operating condition of an industrial boiler, especially a wood pellets-fired one. In order to solve this problem, the paper presents a simplified mathematical model to calculate the
