First, the oil boiler flue gas waste heat utilization technology introduction survey showed, petroleum, chemicals, building materials, textile, printing and dyeing industry has a lot of energy is not being used in production, such as chemical companies cracking furnace, oil furnace and dyeing enterprises heat setting machine, furnace steel companies, these hot exhaust directly emptying a waste of energy and pollute the environment. Waste heat recovery is to re-use waste heat recovery, improve energy efficiency, reduce production costs and protect the environment. Such as oil boiler back to the oil temperature during operation often reaches 240 ℃, while the exhaust gas temperature is reached above 300 ℃. As can the use of heat pipe heat recovery heat recovery over this part, you can heat the water for the production process, heating and bathroom; you can also use steam for production processes which produce clean water by heating. Yu Yao Huaying city Clothing Co. has installed energy-saving devices using this, the actual operating results significantly. This heat pipe heat recovery can be installed in an industrial boiler, furnace flue, the recovery of waste heat into gas - water exchange, producing steam, heating domestic water and boiler water. Constructed as shown: the lower is the flue, the upper part of the tank, the middle partition. Top safety valve, pressure gauge, thermometer interface, tanks have inlet and outlet (steam outlet) and outfall. In operation, the flue gas flows through the heat pipe heat back to the flue side of the lower end of the heat pipe erosion, heat pipe to the upper end of the guide after absorbing the heat, the upper end of the heat pipe heat recovery unit to heat the water, with the increase of water temperature and pressure Production process requires steam. Heat pipe heat recovery steam generator is the use of oil furnace exit flue gas heat carried by high-speed transfer of the heat pipe, the water evaporated to produce steam. Heat pipe is a new type of highly efficient heat transfer element, which is a combination of evaporation and condensation heat transfer in two-phase change heat transfer process, the small thermal resistance, high heat transfer rate, its equivalent thermal conductivity as high thermal conductivity of copper hundreds of times. Two, six heat pipe heat recovery steam generator because of the basic characteristics of ⑴ This efficient heat pipe thermal components, plus heating section of the heat pipe components using high-frequency welding spiral fin to heat transfer, and thus the entire device high heat transfer efficiency, equipment compact, hot flue gas side flow resistance is relatively small; ⑵ the heat transfer from the flue gas into the water, fully completed by the heat pipe components. Water is indirectly heated exhaust gas and water supply completely separated, to avoid the possibility of leakage into the flue of the boiler feed water; ⑶ heat pipe system components are relatively independent, single or several heat pipe damage does not affect system operation; ⑷ single heat pipe design fin evaporator pitch has been adjusted to adjust the transmission power of the heat pipe to control the hot wall temperature, dew point to prevent acid corrosion. In addition to the boiler flue gas side and export outside ⑸ also have to check the door, soot blowing mouth mouth and temperature; the water side of a main steam valve, vent valve, safety valve, water level and so on. Generator feedwater using automatic control, without hand operation. ⑹ compact heat pipe heat recovery steam generator, small footprint, and can be directly installed in the original boiler flue infrastructure investment. Its full use of waste heat, no other energy sources, economic benefit. Third, the energy efficiency analysis and calculation in accordance with the heat pipe heat recovery steam generator technical and economic parameters, energy efficiency is as follows: List of economic parameters and heat pipe heat recovery steam generator technology name, model parameters W (L) RY series of vertical series W ( L) RY-Ⅰ type W (L) RY-Ⅱ type W (L) RY-Ⅲ type W (L) RY-Ⅳ type DN1200 DN1600 Working Pressure (Mpa) 0.9 0.9 0.9 0.9 0.9 0.9 design pressure (Mpa) 1.0 1.0 1.0 1.0 1.0 1.0 flue gas inlet temperature (℃) 280 280 280 280 280 280 Water Temperature (℃) 20 20 20 20 20 20 250 flue resistance 280,310,350,280,280 Rated evaporation t / h 0.2 ~ 0.4 0.4 ~ 0.7 0.6 to 1.1 1.0 to 1.9 0.7 to 1.2 1.3 to 2.2 is equipped with a boiler (× 104kcal) 120-200 250-400 500-700 800-1000 400-600 800-1200 equipped with flue gas volume (Nm3 / h) 4000 ~ 6000 8000 ~ 1200016000 ~ 2400026000 ~ 3200012000 ~ 1800026000 ~ 36,000 automatic control and protection of water protection, automatic pressure relief ultrahigh economic analysis daily earnings: 0.55t / hx20hx140 yuan / t = 1540 yuan / day annual income: 1540x320 = 492800 meter day-by 20 hours, 320 days a year by terms such heat pipe heat recovery steam generator can be used in printing and dyeing enterprises oil boiler exhaust gas to produce steam or hot water recycling; also be used in the chemical industry cracker, catalytic stove and other high-temperature furnace gas to produce steam or hot water for recycling; also be used in steel, steel companies high temperature exhaust gas recycling melting furnace to produce hot water for pickling.
