coal fired hot water boiler

China A-Class manufacturer SZL double drum structure wood chip boiler and biomass boiler for rice mill


1.The DZL type biomass boiler produced by the company is a horizontal three-return tubular boiler. The combustion process of the fuel can be briefly described as follows: the automatic feeding device can throw the biomass fuel into the furnace, and after the fuel is fully burned in the furnace, the high-temperature smoke enters the front smoke through two sets of airfoil flues arranged on both sides of the furnace. The box is then inserted into the rear smoke box through a threaded tube that is inserted into the drum. It is then drawn into the flue, dust collector and chimney by an induced draft fan and finally discharged to the atmosphere. The boiler is safe and stable in operation, easy to operate, and low in failure rate.
2.The main features of biomass boiler: running environmental protection, saving fuel, automatic fuel addition, automatic slag removal, variable frequency adjustment of blower induced draft fan, fully automatic operation of boiler, automatic adjustment of fuel quantity according to load change, stable steam output.

3. It has a number of protection and alarm measures such as pressure, water level and exhaust temperature to ensure the safe operation of the boiler. Henan Yongxing Boiler Manufacturing Plant, for example, has developed a number of core technologies that are widely used in steam boilers produced.

4. It is strongly advocated to use industrial boilers fueled by renewable biomass pellets, which not only reduces energy consumption, but also greatly reduces emissions of carbon dioxide, sulfur dioxide and nitrogen oxides, and effectively improves air quality. At the same time, it responds to the concept of low-carbon energy conservation advocated by China and the world.

Precautions of Biomass boiler use 

1.The specific operation of the boiler should be carried out according to the product manual to ensure the safety of the operators and equipment.
2. Before starting the boiler, check the power supply, voltage, water source, fuel abnormality, close the drain valve, open the water supply valve, and check whether the flue is unobstructed. In addition, check the pressure of the furnace body and the operation of the make-up pump to confirm whether the motor can work normally. Check the working condition of the water pump. If the pump fan blade is stuck, remove the fan blade back cover and turn the motor shaft to the flexible state. After all the above devices have been confirmed, they can be turned on.
3. When the user repairs the boiler or replaces the accessories, the power must be cut off to avoid danger to the operator.
4.The electric control box, burner, pump motor and other parts should avoid moisture ingress to prevent burning, and the boiler should be kept clean.
5.This product belongs to biomass/fired steam boiler. Please be sure to install water softener when using this equipment according to the boiler water quality requirements. Because the hard water quality will cause boiler fouling, it will cause tube explosion when it is serious. Shorten the life of the boiler. Failure to use the water treatment equipment as required to cause damage to the boiler is not covered by the warranty.
6. Please pay attention to the timed sewage when using the steam boiler. Discharge at least once a day and discharge at a pressure of 0.15 MPa to 0.25 MPa. This can effectively prevent pipe blockage. In addition, the sewage pipe should be connected according to the regulations, beware of the operator's burns.
7. If the user asks the company's technical personnel to come to the door, the boiler should be carefully inspected according to the instructions. Because if it is not the quality of the product during the warranty period, the request for on-site service is a paid service.
8.The safety valve should be regularly checked for flexibility. Pull the lever of the safety valve at least once a month to check its flexibility of jumping and returning. The safety valve should be regularly checked by professionals every year.
