2. Indirect gas fuel hot air stove
It is a high-temperature combustion gas obtained by using a fuel after combustion reaction, through various
A heat exchanger in the form to heat the air. It is mainly suitable for the dry materials not allowed to be contaminated, or applied to the drying of heat-sensitive materials with lower temperature. Such as: milk powder, pharmaceutical, resin, fine chemicals. The fire tube is inserted with a flame-retardant spoiler to slow down the smoke extraction speed and enhance heat exchange. The smoke temperature of the smoke chamber is low, reducing heat loss and saving fuel.
1. Direct high-purification gas fuel hot air stove
It is the high-temperature combustion obtained by direct combustion of fuel and the combustion reaction of fuel.
The burning gas is further contacted with the outside air, and after being mixed to a certain temperature, directly enters the drying chamber or the baking room, and comes into contact with the material to be dried, heats and evaporates the water, thereby obtaining a dry product. This method consumes about half as much fuel as steam or other indirect heaters. Therefore, the gas hot air can be completely used without affecting the quality of the dried product.
The fuel is a gaseous fuel such as gas, natural gas, or liquid gas.
As the government vigorously manages environmental pollution, coal-fired boilers will gradually withdraw from the market, while fuel-fired gas boilers are the preferred type for 90% of users, with high degree of automation, automatic purging according to controller instructions, electronic auto-ignition, automatic combustion, wind Oil (gas) automatic proportional adjustment, safe and stable performance, good combustion effect. It also has a flameout protection device to ensure safe operation. The ash, sulfur content and nitrogen content in the gas are lower than that of coal, the combustion is sufficient, the amount of dust in the flue gas is very small, and the emission is easy to meet the national standards for gas fuel oil equipment, which can greatly reduce environmental pollution and environmental protection performance. it is good.
Compared with coal-fired boilers, fuel gas boilers have the following advantages
1. Saving land: fuel gas boilers do not need coal ash dumping, saving land
2, reduce the staff: fuel gas boilers less than coal-fired boilers, less staff, less wages and welfare costs.
3. Low noise: The fuel gas boiler room is flexible in layout, with less floor space and low noise.
