Introductions

The DZL type biomass boiler is a single-drum vertical biomass boiler. The rated evaporation is 1-10t and the power is 0.7-7MW. This type of boiler uses biomass pellets made from straw, sawdust, peanut shells, etc. as fuel. It uses a new furnace design to maximize fuel combustion and heat transfer through the built-in three-return threaded pipe to make the boiler's thermal efficiency.

1. It has reached more than 82%, not only the fuel cost is much lower than that of coal fuel gas, but also the use of farmland waste as fuel for boilers. The burned ash can also be used as farmland fertilizer. Therefore, biomass boiler is still an energy-saving environmental protection. product.

2. When the company designs boilers, it strictly controls the quality of its products and has many core technologies. For the purpose of prolonging the service life of the boiler, the company uses arched tube sheets and threaded tobacco tubes to transform the quasi-steel body of the drum into a quasi-elastic structure.

3. the tube plate area is modified, and the tension members are eliminated. The problem of cracks in the traditional boiler tube sheet greatly improves the use time of the boiler.

4. the threaded pipe also strengthens the heat conduction, further improving the heat transfer coefficient and thermal efficiency of the boiler itself. Therefore, boiler products have a wide range of applications in the food, building materials, washing, smelting, chemical, textile and other industries.

Structural features
1. The boiler is a horizontal quick-install boiler, and the water circulation mode is natural circulation. The boiler heat exchange system consists of a drum, a left and right header, and a water-cooled wall. The main heating surface is designed to install the furnace water wall. In addition, the main heating section of the boiler is made of seamless steel pipe for 20# low and medium pressure boiler, and the drum is made of special steel plate for boiler. The left and right headers are made of seamless steel tubes.
2. The boiler shaft is made of refractory concrete. The rear arch is low and long, so the combustion effect is good. The two-wing flue and the side wall brick are made of refractory sintered brick. General refractory bricks are used for the front and rear walls of the boiler.
3. The material circulation loop of the boiler is well designed, the fuel mix is ​​sufficient, the furnace temperature is uniform, and the biomass fuel combustion efficiency is high. Compared with the traditional coal-fired boiler, the concentration of carbon dioxide, sulfur dioxide and nitrogen oxides in the exhaust gas is very low. Therefore, the pollution of the air during the operation of the boiler is small;
4. The water circulation mode is simple, the structure of the pressure-receiving parts is reasonable, and it can be safely operated under the condition of ensuring water quality. At the same time, high-standard, high-quality auxiliary machines, accessories and automatic control equipment are used to ensure safe and stable operation of the boiler.
5. Automatic control system. The control system adopts high-brightness and full-English display mode. The PLC control system is used as the central control unit. The information exchange between the boilers is realized by man-machine dialogue mode, and the automatic operation of the BMF boiler is fully realized.

Precautions when burning fuel
1. Grate combustion must be monitored regularly so that the combustion of the fuel in the grate and ash outlet area is fully understood.
2. If the fuel on the grate is too small, the ignition will be unstable and the combustion of the fuel will be further hindered.
3. If the fuel on the grate is too much, the combustion is not complete, and the furnace will be burnt and disordered during the vibration of the grate. At this point, low excess air or furnace over pressure can increase the risk of boiler operation.
4. When the vibration amplitude of the grate is too large, some fuel will not be burned and will be discharged into the slag outlet, which reduces the overall thermal efficiency of the boiler.
5. If the amount of air in the upper and upper parts of the grate is too large, the flame front on the grate will be too high. This way the flame is mainly concentrated between the middle and the lower part of the grate, and there is very little flame in the upper part of the grate.
6. If the oxygen content in the flue gas is too high, it indicates that the fuel supply is too small or the vibration of the grate is too large.
