A Study and Simulation on Thermal Cycling System of CFB Boiler

Energy is the main resource for our country to survive. However, in recent years, the excessive consumption of energy has made the environment worse and worse, and made the development of our country restricted. Technology of circulating fluid-bed boiler is the main way of general clean coal at present, and is a hot topic for each country in the world. However, the experimental process of the technology often spend a great cost, therefore is not suitable in practice. So simulation technology of circulating fluid-bed was used in this paper to solve practical problems. This paper established a circulating fluid-bed (CFB) boiler simulation system based on XinXiang HG-440 CFB, and analyzed final simulation system. Simulation process from thermal efficiency to thermal energy transformation were researched based on rules of thermal cycling and outlet of improving thermal energy utilization.This technology can not only improved the efficiency of energy, but also effectively reduced the energy generated in the process of burning gas pollution. Moreover, it has played an important role in China’s energy construction.
