Industrial Furnace Exhaust Heat Recovery And Utilization Of Research

China has a large energy resource consumption and a rather low utilization ratio because of the serious waste of the energy., the economic performance in energy and the energy make use of the technique of the system are bad . the unit of a lot of products cans consume with prosper the nation compares the margin very big, such as the steel, generate electricity, the main industry product unit of the building materials, chemical engineering etc. Profession can consume the high outing 20% - 80%, the hot efficiency of especially various industry boiler is a lot of all lower than 70%, hot utilization in remaining for 4-5%, have the very big economy energy potential , and the temperature of the waste gas vented by industry boiler is higher,commonly reaches 160℃—240℃. So, depend on the technology progresses, making use of the modern hot tube technique, withdrawing the hot value in remaining of the boiler waste gas, reducing the hot row in remaining empty, to hot efficiency and economy the energy has the important meaning.Therefore , design the new low temperature change the hot machine, putting forward from the waste gas hot worth, used for the winter the public keeping warm, realize economy, the society unifies with environment performance, the heat pipe and heat exchanger have been widely used in the boiler industy, mainly used in the recovery and utilization of the low temperature waste heat resourcesA combination the oxidize aluminum factory three car a the spotcircumstances and production craft parameter, with a set φ4.3 × 75m boiler variouscrafts parameter is an example , thinking current velocity, temperature, pressure conduct and actions that basis, consults its waste gas to index sign, compute to change the calories and change the hot area, in consideration of pure ash and increases to change the hot efficiency etc. factor, design an efficiently hot tube for the construction is reasonable change the hot equipments. The heat pipe and heat exchanger have the advantages of high heat transmission efficiency .simple structure, safely and reliability,needing no repairing and additional power.The other boiler is similar of change the design of the hot machine can consult the design way of thinking of the lesson's, compute method etc. proceeding.
