Feasibility Analysis on Flue Waste Heat Power Generation Technology of Silicon Metal Furnace
The aluminum silicon alloy production enterprises has a 25000KVA of high purity silicon metal furnace in China, 350-550℃ process exhaust produced by reaction furnace is directly discharged into the atmosphere now.According to the characteristics of low temperature flue gas, such as flow rate and temperature fluctuate a great deal, silica particles in the flue gas is very fine, strong adhesion and very high resistance dust and so on, This work analyzes the feasibility of utilization of waste heat power generation.Proposed the technical scheme that use waste heat boiler of box type module structure to absorb the waste heat of the flue gas to produce medium temperature and medium pressure steam, and use spiral pole expanding motive machine to drive the generator to transform steam internal energy into high quality electrical energy.This work process is advanced and reliable, energy saving and environmental protection, has good economic benefit and social benefit, and the technology has reached the domestic advanced level.
