Diaphragm air pressure tank is an energy storage device composed of a steel shell and a rubber diaphragm liner. The rubber diaphragm completely separates the water chamber from the air chamber. When water with external pressure is filled into the liner of the diaphragm air pressure tank, the air sealed in the diaphragm air pressure tank will be compressed. Hebei Miniature steam generator According to Boyle's gas law, the volume of gas becomes smaller after being compressed, and the pressure increases to store energy. The expansion of compressed gas can press the water in the rubber diaphragm out of the tank. Diaphragm pressure tank is widely used in central air conditioning, boiler, water heater, frequency conversion and constant pressure water supply equipment. It can buffer the pressure fluctuation of the system and eliminate water hammer to stabilize the pressure and unload the load. small-scale Miniature steam generator how much When the water pressure in the system changes slightly, the automatic expansion and contraction of the diaphragm air pressure capsule will have a buffer effect on the change of water pressure, which can ensure the stability of the water pressure in the system, and the water pump will not be opened frequently due to the change of pressure.

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.

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. small-scale Miniature steam generator 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 waste heat recovery of flue gas can not only be used for heating or power generation to achieve energy-saving effect, but also can be beneficial to environmental protection and achieve dual effects of energy conservation and environmental protection. Hebei Miniature steam generator In general, the important equipment of waste heat power generation is waste heat boiler, which mainly uses heat or combustible substances in waste gas, waste liquid and other working medium as heat source, and produces steam mainly for power generation. There are many ways to recover waste heat from flue gas of waste heat boiler. Generally, comprehensive utilization of waste heat is followed by direct utilization and indirect utilization. small-scale Miniature steam generator how much Generally speaking, if heat sources are needed in the process, the waste heat utilization is mainly comprehensive utilization. First, the heat source is recovered and fed back to the process for reuse. If there is any surplus, it can be used for power generation or as the heat source for central heating; If there is no surplus, it will be directly used instead of being used for power generation; If the process does not need more heat sources, then indirect use, mainly power generation or public heating.

Most softened water equipment can only slow down the scale growth rate, but can not achieve the purpose of scale prevention. The water quality used by different users varies greatly in different regions. Hebei Miniature steam generator In some construction sites, steam generators are used for steam maintenance of bridges because tap water cannot be used due to conditions. Only groundwater or river water can be used. At present, the hardness of many groundwater in China exceeds the standard, and the total hardness of water in some areas is high. small-scale Miniature steam generator how much It can reach several hundred millimoles, which is quite serious. I think the use of water softener is basically ineffective, because ordinary resin exchange water softener can only affect water with hardness of 7, which also ensures the use process. It needs to be cured regularly.

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. Hebei Miniature 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 Miniature steam generator how much 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.

The waste heat boiler has advantages in the subdivided industry and is the leading enterprise in the industry. The company's main products are various types of waste heat boilers, industrial boilers, power station boilers, nuclear power equipment and power station auxiliaries. It is a research, development, design and manufacturing base for waste heat boilers with large scale and complete varieties in China. Hebei Miniature steam generator Waste heat boiler is a typical energy-saving and emission reduction equipment. Its heat source can come from high-temperature flue gas waste heat, chemical reaction waste heat, combustible waste gas waste heat, and even can use high-temperature product waste heat. At present, the company has more than 20 series and more than 100 varieties of waste heat boiler products, which are widely used in steel, building materials, power, nonferrous metals, coking, chemical and other industries. small-scale Miniature steam generator how much In 2008, the company produced 272 sets of waste heat boilers of various types, with a total of 10268 steam tons, accounting for 34% of the comprehensive market share based on steam tons; According to the output value, the market share is 47%, ranking first in the waste heat boiler industry.
