Heat Recovery System

Listing ID #390839

In present scenario competition exists in every field of business. Margins are becoming less and expenses are increasing more day by day. Margins can be raised only by energy saving. In the re-rolling mill sector nothing is in control of the owner of a mill, neither the price of raw material nor price of finished goods. The only thing that a mill owner can do is proper utilization of resources and saving of energy. Energy saving is equivalent to energy created. The routine process in rolling mills is that the raw material is heated up to approx. 1200ºC and then passed through rolling section. When the flue gas moves from furnace to draft then it has temperature of about 450-550ºC. Heat at this high temperature goes as a waste through the chimney. This sensible heat loss by flue gases can be recovered by means of a waste Heat Recovery System, which leads to energy savings on account of fuel. In this regard we have introduced a Heat Recovery System (Recuperator) especially for re-rolling mills that mainly use coal. Heat Recovery System and Air Heaters are Waste Heat Recovery Equipment that use energy in hot waste flue gases to preheat combustion air. By using Heat Recovery System, we have received preheated air temperature in the range of 250- 300ºC. This Heat Recovery System is installed over the draft. Therefore no chocking problem occurs in Heat Recovery System. By using 10-15% of fuel saving can be achieved by the implementation of Heat Recovery System. The scale loss that plays an important role in re-rolling mill is also reduced up to very great extent. Heat Recovery System’s pay back period is 6 months. By the implementation of recuprator emission level of CO2 and SPM level reduced which ultimately increase the life of APCD.
