What's the price of a hot blast stove?

The price of hot blast stoves is about 10,000 to 20,000 yuan per set/kloc-0, ranging from several thousand yuan cheaper to several tens of thousands more expensive. Different types of hot blast stoves have different prices. As far as category is concerned, direct high purification hot blast stove. That is, the fuel is directly burned, and after being highly purified, hot air is formed, which is directly contacted with materials for heating, drying or baking. This method consumes about half as much fuel as steam or other indirect heaters. Therefore, direct high-purity hot air can be used without affecting the quality of dried products. Fuels can be divided into: ① solid fuels, such as coal and coke. ② Liquid fuels, such as diesel, heavy oil and alcohol-based fuels. (3) gaseous fuels, such as gas, natural gas and liquefied gas. The high-temperature combustion gas obtained after the fuel combustion reaction is further contacted with the outside air, mixed to a certain temperature, directly enters a drying room or a drying room, contacts with the dried material, and is heated to evaporate water to obtain a dried product. In order to utilize the heat of combustion reaction of these fuels, it is necessary to increase fuel combustion devices. Such as: coal stoves, oil stoves, gas stoves, etc. This direct-heating hot blast stove can't be used for heating such as breeding. 1。 Indirect hot blast stove Mainly suitable for drying materials that are not allowed to be polluted, or heat-sensitive materials with low drying temperature. Such as: milk powder, medicine, synthetic resin, fine chemicals, etc. This heating device takes steam, heat transfer oil and flue gas as carriers, and heats air through various forms of heat exchangers. The more essential problem of indirect hot blast stove is heat transfer. The larger the heat exchange area, the higher the heat conversion rate, the better the energy-saving effect of the hot blast stove, and the longer the life of the furnace body and heat exchanger. Conversely, the size of the heat exchange area can also be determined from the flue gas temperature. The lower the flue gas temperature, the higher the heat conversion rate and the larger the heat exchange area. After the fuel is separated from the heat source, it can be used for human body heating. The working principle can be divided into two types: heat storage type and heat exchange type. Regenerative type, according to the different regenerator inside the hot blast stove, can be divided into spherical hot blast stove and checker brick hot blast stove. According to the combustion mode, it can be divided into top combustion, internal combustion and external combustion. How to improve the air temperature is the long-term research direction of the industry. Common methods include mixing high calorific value gas, increasing the heat exchange area of checker bricks of hot blast stove, changing the material and density of checker bricks, or changing the shape of heat accumulator (such as heat accumulator ball), and preheating gas and combustion air by various methods. Advantages: high heat exchange temperature and high heat energy utilization rate. Disadvantages: large volume, large floor space, unstable hot air temperature, many switch mechanisms, easy to cause problems, short service life of heat accumulator, high maintenance cost and extremely high purchase cost. Heat exchange type, mainly uses high temperature resistant heat exchanger as the core component, and this component can only use high temperature resistant ceramic heat exchanger, but not metal heat exchanger. The gas is fully burned in the combustion chamber, and the hot air after combustion exchanges heat with fresh cold air through the heat exchanger, so that the temperature of fresh air can reach 1000 degrees or above. Advantages: high heat exchange temperature, high heat utilization rate, small volume, stable hot air temperature, many switching mechanisms, long service life, high maintenance cost and low purchase cost. Disadvantages: the heat exchange temperature is not as high as that of regenerative type, which appears late and is not widely used. 1。 If you want to know more information and price of hot blast stove, you can consult Wuxi Dafeng spray drying equipment co., ltd, thank you!
