Development of A Hot Water Boiler System with A Rice Hull Furnace -Development of A Mathematical Model of Simulation-

왕겨 연소기(燃燒機)를 이용(利用)한 온수(温水)보일러 시스템 개발(開發)(II) -시뮬레이션 모형(模型) 개발(開發)-

A mathematical model was developed and programmed for computer simulation of a prototype hot water boiler system with rice hull furnace to predict the temperature distributions in the rice hull furnace and water tank, mass flow rate of hot water and thermal efficiency of the system under various operation and design conditions. The effects of feed rate of rice hull, thickness of the furnace wall, the type of heat exchanger, diameter of the water circulation pipe, etc, on the performance of the system can be evaluated with this model. The validity and simulation results of this model will be published in the next paper.
