It can only be prevented by adding medicine to the pot. Zhejiang Natural gas steam generator Adding drugs to the boiler can further soften the water quality, making up that the softening water equipment cannot replace silicon, sulfur and heavy metal ions and anions, so that impurities such as suspended solids, water slag and scale in dissolved water have good looseness and fluidity, and then the impurities are discharged by sewage, thus preventing scale. The water treatment method is carried out in the pot, so it is called water treatment method in the pot. vertical Natural gas steam generator how much Therefore, boiler water treatment actually includes water treatment of feed water and quantitative feeding treatment in the boiler. Water treatment should only be carried out without adding drugs. The boiler water index basically does not meet the specified requirements, and the boiler cannot operate under good water quality. This is also the main reason for the softened water device. The softened water is also qualified, and the boiler will also be polluted.

The boiler adopts the combustion equipment suitable for the combustion of biomass fuel - reciprocating grate. In the structural design of the boiler, the furnace space of the boiler is larger than that of the traditional boiler, and the reasonable arrangement of the secondary air is conducive to the full combustion of a large amount of volatile matter released instantaneously during the combustion of biomass fuel. The boiler can be equipped with oil (gas) ignition burner to realize ignition automation. Zhejiang Natural gas steam generator The feeding, combustion, slag removal, water supply and ignition of the boiler can be automatically controlled, and the operation is convenient. The boiler is equipped with an automatic ash cleaning device, which can remove the ash on the heating surface of the boiler in time to ensure the efficient and stable operation of the boiler. The tail of the boiler is equipped with an economizer, or an air preheater according to the user's needs. Compared with the traditional boiler, the boiler has higher efficiency and lower exhaust gas temperature. High efficiency thermal insulation materials are used, the boiler surface temperature is low, and the heat dissipation loss can be ignored. vertical Natural gas steam generator how much All pressure parts are made of excellent boiler steel in strict accordance with Chinese national codes and standards. Each boiler shall be strictly inspected and tested before leaving the factory, including hydrostatic test and X-ray inspection. Manholes, inspection doors, fire observation holes, etc. are set to facilitate maintenance. The major characteristics of biomass boiler are: energy conservation, environmental protection, and easy installation and use.

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. Zhejiang Natural 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 Natural gas steam generator how much 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.

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. Zhejiang Natural gas 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 Natural gas steam generator how much 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.

The main parts of the waste heat boiler can be divided into drum, pipe, header, membrane wall, tube panel, tube box, etc. These parts are the parts with specific process requirements in the waste heat boiler. Zhejiang Natural gas steam generator For example, the drum should go through metal flaw detection, heat treatment, hydrostatic test and other processes to improve the stability of the waste heat boiler. At the same time, because the header needs high sealing, manual welding is required, and the welding quality needs to be tested. It can be seen that due to the complexity of the working environment of the waste heat boiler, it has special requirements for its internal structural members. vertical Natural gas steam generator how much In the process of designing and manufacturing the waste heat boiler, the process designer should consider the advantages and disadvantages of various processes, and then select a reasonable process to complete the manufacturing of the waste heat boiler. For example, the serpentine parts in the waste heat boiler cannot be bent automatically by the machine, so they can only be bent manually.

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. Zhejiang Natural 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 Natural gas steam generator how much 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.
