       Boiler GrateHow to maintain the grate during operation?

　　The boiler grate is a long-established, reliable, and stable mechanical coal-burning device used in industrial boilers, and it has been widely applied. So how to maintain the grate during operation?

　　Boiler GrateHow to maintain the grate during operation?

　　There are different operating methods when the grate is running, but from the current situation, we can see how to operate effectively. Most people probably do not understand how to maintain it during the operation process. Monitoring various methods of the grate. In the actual monitoring process, all fan oil pumps or water pumps need to be monitored. However, during the monitoring process, there will be different operating methods for the two clean and three touch operations of the grate section. However, from the current situation, it can be seen how to operate effectively.

　　The operation of water treatment equipment during the actual operation of the grate can be regularly checked. Regardless of whether the ion exchange in the equipment has failed, backwashing needs to be performed regularly.

　　Monitoring flue gas temperature. Generally, the flue gas temperature of these boilers is relatively low, and it will gradually increase with the extension of operating time. If these changes exceed 20, the chain grate needs to choose an appropriate time to stop cleaning the ash. If this situation occurs frequently, it is necessary to check whether the system is normal. If the oil pressure is too low and the oil temperature is low, it may lead to poor atomization. Or if the air-oil ratio is incorrect, it may cause a lack of oxygen in the oil-gas mixed combustion.

　　How to effectively maintain the grate during use, in addition to paying the above wages, all equipment such as water must also be monitored. Regular sampling and testing should be conducted, and the testing personnel should determine the quantity and frequency of related wastewater discharge. Detailed records of testing and wastewater discharge can be tested through automatic control.

　　Boiler Grate:What are the functional characteristics of different types of chain grates?

　　1. Functional characteristics of chain belt type chain grate

　　The name comes from its shape. It looks like a chain belt, which is a wide circular chain belt linked together. The chain belt is surrounded by sprockets and supported on the front and rear axles. Therefore, it is called a chain belt grate. Currently, the quick-install chain grate boiler from Zhongzheng Boiler mainly uses large chain grates, with tonnage ranging from 1 to 20 tons/hour.

　　2. Functional characteristics of scale type chain grate

　　The scale type grate has many advantages, among which the most obvious is less coal leakage, the ability to replace scales without stopping the furnace, uniform ventilation, and a relatively small ventilation cross-section (6%). The chain grate plates that are exposed to high temperatures are not stressed, and the chains under tension are not affected by high temperatures, thus improving the working conditions of the chain grate.

　　3. Functional characteristics of beam type chain grate

　　Beam typeBoiler GrateThe main feature is that it can greatly expand the width and length, allowing for larger boiler tonnage. Currently, domestic beam type chain grate boilers can reach a tonnage of 240 tons/hour. At the same time, the grate has a long service life, is durable, has a stable arrangement, and is easier to replace.
