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. Shanghai Miniature 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. vertical Miniature 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.
The flue gas waste heat recovery device also has the following characteristics: 1. Energy saving. It uses new heat exchange fins and heat exchange elements to make heat exchange more fully, and the exhaust gas temperature can be reduced to 40 ℃~80 ℃; The boiler efficiency can be increased by 6~15%, and the condensate drainage structure can fully recover the latent heat in the flue gas, with remarkable energy-saving effect. Shanghai Miniature steam generator Due to the special structure, the total pressure drop is small and the power consumption is small, that is, the smoke pressure drop is small and meets the system requirements. 2. Beautiful. Due to the use of efficient heat exchange elements and reasonable structural configuration, this product has the characteristics of compact structure, small size, beautiful appearance, etc. vertical Miniature steam generator how much Durable. The heat exchange tube of the flue gas waste heat recovery device is made of stainless steel aluminum fins for efficient anti-corrosion. The thermal stress, anti-corrosion performance and strength are fully considered when the equipment is manufactured, which can ensure the safety, reliability and stability of the equipment, with a service life of more than 25 years.
Gas steam generator is also called gas steam boiler. The steam temperature is not high when the steam gas and steam generator has a fault. How can we solve this problem. Shanghai Miniature steam generator Generally, there are two situations: physical characteristics of water vapor: it will evaporate when reaching 100 ℃, and it is impossible for steam to reach a higher temperature. Although the measured temperature of steam is higher when it receives pressure, the temperature will drop to 100 ℃ as soon as it reaches normal atmospheric pressure. vertical Miniature steam generator how much The way not to imagine that the pressure of the steam engine will rise is to make the steam negative pressure. Every increase of about 1kg in steam pressure will increase the steam temperature by about 10 ℃, so by analogy, you need to increase the pressure as much as you need the temperature. I hope it is useful to you.
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. Shanghai Miniature steam generator 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 Miniature steam generator 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. Shanghai Miniature steam generator 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 Miniature steam generator 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.
