Oil gas boilers have obvious characteristics. The main fuel is oil or gas. According to their functions, they can be divided into steam boilers and hot water boilers. Most of them are designed with large furnaces, with thermal efficiency of more than 98%. At the same time, they also have the characteristics of fully automatic and safe operation. Shanghai Fuel gas steam generator Generally speaking, oil and gas boilers adopt excellent boiler body design. WNS horizontal boiler adopts wet back three return structure, which can reduce the exhaust gas temperature and make the boiler thermal efficiency reach more than 90%. Therefore, the combustion efficiency is relatively high, greatly extending its service life. vertical Fuel gas steam generator manufactor In addition, in the design of oil and gas boiler, there are often hinged front and rear smoke boxes. The maintenance method is simple. Most of them are insulated with light aluminum silicate fiber to reduce heat loss. The external use of all stainless steel plate skin improves the appearance quality. In addition, the oil and gas boiler is equipped with an excellent combustion machine, which greatly improves its stability. The combustion machine has an automatic purging function, It can also prevent deflagration during ignition.

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. Shanghai Fuel gas 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 gas 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.

To understand the advantages and disadvantages of hot blast stove and hot water stove, we should start from the working principles of the two boilers. The hot water boiler can increase the indoor temperature by burning hot water, circulating hot water, heat dissipation, etc. General purpose (radiators, floor heating pipes, water heating air conditioners are generally used for heating in families, enterprises and institutions). Shanghai Fuel gas steam generator The hot blast stove can increase the indoor temperature by heating the air. Generally, a hot channel wind belt is required. It is generally used for workshop, breeding, planting and special heating or drying. Most areas in northern China are cold, such as the three northeastern provinces, Inner Mongolia, Xinjiang and other cities. The colder temperature is more than minus 40 degrees Celsius. There are hot water boilers and steam boilers for heating. Its disadvantage is that it is afraid of circulatory system failure or power failure. vertical Fuel gas steam generator manufactor Once the power failure exceeds two to three hours, if the insulation is not good, the pipeline will freeze. The heating of hot blast furnace is not frozen, and the temperature can be set. It can save 40% energy than hot water heating and 50% energy than steam boiler heating. This comparison is practical. The hot blast stove does not need to apply for a use certificate, the steam boiler and pressure hot water boiler need to apply for a use certificate, and the functional department also needs to carry out annual inspection every year, but also has to bear the cost.

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. Shanghai Fuel gas 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 gas 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.

As a pressure vessel, waste heat boiler shall be used reasonably and managed scientifically in the process of use to avoid safety accidents caused by improper use and management. The quality of water is one of the important factors affecting the service life and safe operation of waste heat boiler. The quality of water added into the boiler directly affects the normal operation of waste heat boiler. Shanghai Fuel gas steam generator The normal delivery of water is the lifeblood of normal boiler use. If the boiler is short of water, it is bound to cause major safety accidents and fatal damage to the boiler. Therefore, it is necessary to ensure continuous and stable water transmission during boiler operation. vertical Fuel gas steam generator manufactor Regardless of the tonnage of the waste heat boiler, the lower configuration of the boiler electric control shall ensure the continuous operation of the boiler water pump, and the water supply pipeline shall be equipped with a water supply regulating valve with good regulation characteristics to control the water supply flow according to the level of the boiler. In addition, in order to ensure that the normal delivery of water will not be affected by the pump failure, a standby pump should be ensured.
