Stainless steel for pressure vessels and its welding characteristics. The so-called stainless steel refers to the addition of a certain amount of chromium in the steel to keep the steel in a passive state and free from rust. Xinxiang Natural gas steam generator For this purpose, the chromium content must be more than 12%. In order to improve the passivity of steel, it is often necessary to add nickel, molybdenum and other elements that can passivate steel into stainless steel. Stainless steel is generally referred to as stainless steel and acid resistant steel. Stainless steel companies do not have certain acid resistance, and acid resistant steel generally has a good stainless property. small-scale Natural gas steam generator how much According to its steel structure, stainless steel can be divided into four categories, namely, austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and austenitic ferritic duplex stainless steel.

The steam used in the steam generator of the hotel laundry is usually 0.4~0.6MPa saturated steam. The working temperature of steam is not very high. Xinxiang Natural gas steam generator The steam boiler of the hotel requires high steam efficiency due to operating costs, so it can save operating costs. The area of the hotel is relatively limited, so the steam boiler with small floor area must be selected. In order to control the investment cost and heat loss of the steam pipe, the steam boiler is usually placed on the side of the laundry room. small-scale Natural gas steam generator how much The steam equipment in the hotel laundry room can only be turned on when washing, not when washing. Therefore, the steam generator is required to start steam production quickly. Laundry equipment is sometimes opened a lot and sometimes less, so the steam boiler is required to adjust the steam volume within the specified range.

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 Xinxiang Natural 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 Natural gas steam generator how much 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.

The waste heat boiler is composed of drum, movable smoke hood, feeding pipe groove, oxygen lance mouth, furnace mouth section flue, inclined section 1 flue, inclined section 2 flue, last section 1 flue, last section 2 flue, nitrogen sealing device and nitrogen sealing plug, manhole, micro differential pressure tapping device, flue support and hanger. Xinxiang Natural gas steam generator Unlike conventional boilers, waste heat boilers do not produce combustion process and do not have combustion related equipment. Essentially, they are just gas water/steam heat exchangers. The waste heat boiler is divided into six circulation loops. Each circulation loop is composed of downcomer and riser. The feed water of each section of flue is introduced from the drum through downcomer to the lower header of each flue, and then enters into each heating surface. The water passes through the heating surface and generates steam into the header, and then is introduced into the drum through the riser. small-scale Natural gas steam generator how much The needle tube waste heat recovery device is a special high-efficient energy-saving product specially designed for waste heat recovery of flue gas. The heat recovery boiler uses needle shaped tubes to strengthen the heat elements to expand the heating surface. The heating surface on the water pipe smoke side can be greatly increased. At the same time, the smoke will form strong turbulence when passing through the needle shaped tube surface, which will improve the heat transfer efficiency and reduce the soot accumulation.
