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. Hunan Energy saving 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 Energy saving 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 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. Hunan Energy saving 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 Energy saving 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.

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. Hunan Energy saving 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 Energy saving 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 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. Hunan Energy saving 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. small-scale Energy saving 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.
