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. Sichuan Gas fired hot blast stove 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. vertical Gas fired hot blast stove 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.
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. Sichuan Gas fired hot blast stove 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 Gas fired hot blast stove how much 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.
Biomass boilers can be roughly divided into two categories according to their uses: one is biomass thermal energy boiler, and the other is biomass electric energy boiler. Sichuan Gas fired hot blast stove In fact, the principle of the two is basically the same. Both obtain energy by burning biomass fuel, which is just one way to directly obtain heat energy. The second way is to convert heat energy into electric energy. Among the two boilers, one is widely used and has mature technology. If we continue to subdivide, one kind of boiler - biomass heat energy boiler mainly has the following two types: one is small biomass heat energy boiler. vertical Gas fired hot blast stove how much The boiler uses solidified or gasified biomass fuel to provide heat energy in the form of hot water. Its advantages are small size, simple structure and low price; Class II: medium-sized biomass heat energy boiler. Such boilers mainly use solidified biomass fuel to provide hot water or steam. Its advantages are relatively mature technology, small energy loss and strong heat supply capacity.
The manufacturer of the pneumatic water tank shall hold the pressure vessel manufacturing license or registration, and have a sound quality management system and system. Sichuan Gas fired hot blast stove The purchased parts of the equipment must have the product certificate and pass the entrance inspection before use. The pneumatic water tank, water pump unit, electrical components and other components of the three-dimensional elastic filler manufacturer's equipment shall be assembled and used after passing the inspection. The equipment assembled on site can be used to inspect the performance of the whole machine on site. The production license issued by the relevant department shall be held. vertical Gas fired hot blast stove how much When selecting this product, requirements shall be put forward for the following items: equipment composition, equipment classification, equipment working pressure, equipment design flow, specification and quantity of air pressure tank, equipment data, and sanitary requirements. The overall structure of equipment, water pipe, gas pipe and electrical circuit shall be arranged reasonably, and the manufacturer of single hole mold aerator shall reserve space for device maintenance to facilitate operation. The pipeline of the equipment shall be equipped with a safety valve, and the opening pressure of the combined packing manufacturer shall not be greater than 1.1 times of the working pressure. The equipment shared by fire fighting and living (production) shall have a separate fire water outlet.
