You will find that the characteristics of industrial boiler equipment are obvious. When designing industrial boilers, they should be regularly maintained. Vertical boilers have obvious characteristics Gansu Horizontal gas steam generator The combustion part adopts a double-layer grate combustion chamber, which has fast temperature rise and pressure rise, reasonable overall layout, good heat transfer, sufficient combustion, smoke suppression and dust removal for unburned gas after secondary combustion, and is one of the smaller steam and heating equipment. small-scale Horizontal gas steam generator factory The characteristics of the whole industrial boiler are obvious, with high thermal efficiency and sufficient steam. The whole industrial boiler is equipped with excellent safety valve, pressure regulator, low water level and other multiple protection devices, which can effectively ensure the safe operation of the boiler. Moreover, industrial boiler equipment is compact in structure, small in floor area, elegant in shape and bright in color. Therefore, it plays an important role in many large factories and coal mining enterprises.

Inspection and use preparation of oil and gas boiler. Inspection of the furnace and flue, and the soot and sundries in the furnace and flue shall be removed. Gansu Horizontal gas steam generator Check the boiler accessories to see if they are in good condition; Whether the cock can rotate easily; Whether the instruments and control devices are in good condition and clean. After inspection, the pressure gauge cock shall be in working condition. Check the automatic control system. Check the auxiliary equipment of oil and gas boiler. Check the combustion equipment to see if the combustion equipment is in good condition; For mechanical transmission system, coal handling system and ballast system, the test steering is normal; The spring of the gearbox shall be properly compressed and lubricated; The indication of coal door gauge is correct. small-scale Horizontal gas steam generator factory The eagle iron is neat and complete, and the ballast plate is complete. Check the heating surface and ensure that the equipment coupling is firmly connected; V-belt is loose properly; The lubricating oil is in good condition; The cooling water is smooth. After passing the test, install the protective cover, test run separately, and pay attention to the current during idling.

High heat exchange efficiency. The fusion rate at the contact is more than 95%, the contact thermal resistance is small, and the thermal conductivity is good. Low flow resistance. Gansu Horizontal gas steam generator Since H-shaped finned tubes are similar to square structures, after being assembled into heat exchangers, the tubes are divided into many small channels by fins, which has a certain uniform effect on the air flow. The air flow is similar to longitudinal downstream flow, and the air flow resistance is relatively small. However, spiral finned tubes have strong air flow disturbance, high turbulence, and large air flow resistance due to the directivity of the fins. Less ash. The flue gas contains fly ash, which is easy to deposit on the windward side and leeward side of the pipe bundle. The H-shaped fin tube bundle has the characteristics of uniform flow and downstream flow, so it is not easy to cause serious local ash deposition, and the fly ash can be taken away with the air flow in time. Therefore, compared with spiral finned tube heat exchanger, H-type finned tube heat exchanger has less ash deposition. small-scale Horizontal gas steam generator factory Small size and low weight. H-shaped finned tube has high area expansion rate, less ash deposition, and high heat transfer efficiency. When the heat transfer capacity is equal, the space occupied by the heat exchanger can be small. For reconstruction projects, the heat exchange area can be arranged as much as possible in the limited space to reduce the exhaust gas temperature, improve the waste heat recovery efficiency, or increase the maintenance space to facilitate maintenance.

The furnace liner is the combustion chamber of the horizontal gas-fired heat transfer oil furnace. The burner nozzle is placed in the front of the furnace liner, and the high-temperature flue gas generated by combustion extends to the rear, leaving the furnace liner and returning to the space. Generally, the number of times of returning is not more than four, and the common one is the three return heat conduction oil furnace. Gansu Horizontal gas steam generator This type of heat transfer oil furnace can be divided into dry back type heat transfer oil furnace and full wet back type heat transfer oil furnace according to the structure of the flue gas reentry space at the rear of the furnace. The flue gas reentry space of the dry back heat conduction oil furnace is enclosed by refractory materials; The flue gas reentry space of the full wet back type heat conduction oil furnace is composed of a recuperative chamber immersed in water. In addition, there is a central regenerative heat conduction oil furnace: that is, the back wall of the furnace liner is sealed inside the boiler shell, and the flue gas is turned back to the front from the inner wall around the furnace liner after encountering. This type of heat transfer oil furnace can also be regarded as a full wet back heat transfer oil furnace. small-scale Horizontal gas steam generator factory Although the dry back heat transfer oil furnace is simple in structure, the refractory material at the rear of the furnace liner is easily damaged, and the rear tube plate is often directly washed by high temperature flue gas. The temperature difference is large, so the dry back heat transfer oil furnace is obsolete. At present, few manufacturers produce it; Although the full wet back heat conduction oil furnace has a complex structure, it avoids the problem of flue gas sealing in the reentry space and is suitable for micro positive pressure combustion.

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. Gansu Horizontal 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. small-scale Horizontal gas steam generator factory 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.
