Simulation of Solid-Fuel Hybrid Combustion
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2017, Vol 21, Issue
Abstract
Solid-fuel utilization in the public energy service is necessary for national supply-demand balance stability. The most efficient combustion process is the hybrid combustion, particularly the three-staged one: combination of stack, fuel-bed firing and overall combustion in swirl chamber. Stability of such combustion model is achieved by relevant design and duty parameters at all stages of fuel combustion with appropriate blasting air reallocation and process flow. A numerical model is proposed in a mechanized boiler with the use of a hybrid process. Analytical equations for calculating the main parameters of the combustion zone in the stack and on the grate are provided. The use of the proposed model for the combustion of solid-fuel provides a definition of parameters of the combustion zone at the stage of designing a boiler plant with mechanized combustion
