Oil boiler exhaust heat recovery due to the use of oil heating using steam heating compared with the existing uniform heating, easy operation, safety and environmental protection, energy saving, high precision temperature control, and low operating pressure, in modern industrial production has been as heat transfer medium is widely used in the textile industry, oil boiler sizing device is mainly used for drying, hot melt dyeing means dyeing and printing equipment, dryers, dryer, calender, pressing machine, washing machine , mangle, ironing machines, hot air tenter like heating. While high oil boiler efficiency, flue gas discharge temperature is relatively high, generally about 300 degrees of heat, resulting in waste heat, so the recovery of this part of the heat will be a very considerable economic benefits. Our oil boiler exhaust heat recovery equipment is used in heat pipe technology, the characteristics of heat pipe heat efficiency is very fast heat is a heat transfer element having a high conductivity properties, which closed by evaporation of the working fluid in the evacuated envelope and condensation to transfer heat, with a high thermal conductivity, good isothermal, hot and cold sides of the heat transfer area can be arbitrarily changed, long-distance heat, temperature-controlled series of advantages. Oil boiler exhaust heat recovery of flue gas heat recovery equipment, can produce needed hot water, hot air or steam, a day can produce much steam or hot water or hot air, is what we are most concerned about, which is directly related to the device for the enterprise economic benefits. We will be based on the actual situation of the boiler to the site to measure, according to the exhaust gas temperature and flue gas volume for the enterprise to design a most appropriate program, to create the greatest economic benefits for enterprises.
