The flue gas waste heat recovery device also has the following characteristics: 1. Energy saving. It uses new heat exchange fins and heat exchange elements to make heat exchange more fully, and the exhaust gas temperature can be reduced to 40 ℃~80 ℃; The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas, with remarkable energy-saving effect. Yunnan Fuel oil steam generator Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. 2. Beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, this product has the characteristics of compact structure, small size, beautiful appearance, etc. vertical Fuel oil steam generator manufactor Durable. The heat exchange tube of the flue gas waste heat recovery device is made of stainless steel aluminum fins for efficient anti-corrosion. The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.

Most softened water equipment can only slow down the scale growth rate, but can not achieve the purpose of scale prevention. The water quality used by different users varies greatly in different regions. Yunnan Fuel oil steam generator In some construction sites, steam generators are used for steam maintenance of bridges because tap water cannot be used due to conditions. Only groundwater or river water can be used. At present, the hardness of many groundwater in China exceeds the standard, and the total hardness of water in some areas is high. vertical Fuel oil steam generator manufactor It can reach several hundred millimoles, which is quite serious. I think the use of water softener is basically ineffective, because ordinary resin exchange water softener can only affect water with hardness of 7, which also ensures the use process. It needs to be cured regularly.

In the chemical industry, the electric heating heat conduction oil furnace is used for distillation, evaporation, polymerization, condensation, steel gate, fatliquoring, monotony, melting, dehydrogenation, forced heat preservation, and the heating of equipment composed of pesticides, intermediates, antioxidants, surfactants, spices, etc. Yunnan Fuel oil steam generator In the plastic and rubber industries, the electric heating heat conduction oil furnace should be used for heating and insulation of hot pressing, hot rolling, kneading, kneading, internal mixing, vulcanization molding, jet injection molding machine, slurry mixer, conveyor belt dryer, screw kneading machine and mold. In metallurgy, machining and casting industries, electric heating heat conduction oil furnaces are used to heat metal degreasing tanks, dewar tanks, electric gate valves, cleaning tanks, electroplating tanks, aluminum plate oxidation tanks, electrode manufacturing, shower heat treatment equipment, phosphate treatment equipment, baking machine rooms, sand core drying, varnish spraying and monotonous equipment. vertical Fuel oil steam generator manufactor In the food industry, the electric heating heat conduction oil furnace should be used for bread baking equipment, biscuit food baking equipment, candy production equipment, grain monotone equipment, cooking oil pressing and refining equipment, distillation pot, autoclave, conveyor belt dryer electric heater equipment.

The existing industrial boiler flue gas waste heat recovery equipment mainly includes tubular heat exchanger and full heat pipe heat exchanger. Tube and tube heat exchanger can be composed of finned tube bundles. The advantage of finned tube is that it can withstand higher temperature, but has low heat transfer coefficient and large floor area. Yunnan Fuel oil steam generator The flue gas of industrial boilers contains sulfur and other acidic substances. In the low temperature zone (flue gas outlet section), the temperature may be lower than the dew point of the acidic substances. The acidic substances will dew on the pipe wall, corrode the shell of the fin tube. The fin tube heat exchanger has poor operating reliability and low service life. vertical Fuel oil steam generator manufactor The total heat pipe heat exchanger of boiler flue gas waste heat recovery equipment is composed of heat pipe bundles. Its shell is made of multi-layer composite materials. The heat pipe structure is complex, the cost is relatively expensive, the service life is short, and the steel consumption is large. It is difficult for users to accept it, and it is difficult to promote its application in production. The composite heat pipe heater not only takes into account the heat exchange effect, but also takes into account the economic affordability of the investors in production, which is particularly suitable for the current situation in China's industrial production.

After the cold furnace of oil fired and gas fired boiler is ignited, the speed of temperature rise shall be controlled at 10 ℃/hour, mainly because the viscosity of oil temperature is large when it is cold, and the flow rate in the heating surface pipe of the whole equipment is relatively low. Yunnan Fuel oil steam generator The oil film on the pipe wall is thick, so the heat transfer condition is poor when in use. If the heating speed of oil and gas fired boiler is too fast during use, it is easy to make the local oil film temperature too high. The equipment is in the stage of driving away the residual moisture and moisture contained in the heat conduction fluid in the system within the temperature range. vertical Fuel oil steam generator manufactor In oil and gas fired boiler, when the steam exhaust volume at the vent pipe of the expander is relatively large, there will be water hammer at the bottom of the equipment. In this way, the vibration of the pipeline will accelerate, and when the swing amplitude of the pressure gauge pointer in each part of the equipment is large, the temperature rise will be stopped and the constant temperature state will be maintained.

Most people may already know something about flue gas waste heat recovery, because they have already explained a lot about it. In order to let you know the relevant knowledge of flue gas waste heat recovery, the following is a brief introduction to the two methods commonly used for recovery. Yunnan Fuel oil steam generator Two methods are usually adopted for flue gas waste heat recovery: one is to preheat the workpiece; The other is to preheat air for combustion support. The flue gas preheating workpiece needs to occupy a large volume for heat exchange, which is often limited by the operation site (this method cannot be used for furnaces that are used intermittently). vertical Fuel oil steam generator manufactor Preheating air for combustion support is a good method. It is generally configured on the heating furnace, which can also strengthen combustion, speed up the temperature rise of the furnace, and improve the thermal performance of the furnace. This can not only meet the requirements of the process, but also achieve significant comprehensive energy-saving effect.
