How To Improve The Thermal Efficiency Of Boiler

Boiler thermal efficiency is the boiler in the working process of the heat generated by the boiler and the boiler input fuel calorific value of the ratio between the boiler is to reflect the efficiency of boiler energy utilization of important technical indicators. There are many factors affecting the thermal efficiency of the boiler, mainly including the following aspects:

1. Boiler design: including boiler form, structure, material and so on. Reasonable boiler design can reduce heat loss, improve combustion efficiency, thereby improving boiler thermal efficiency.
2. Fuel quality: the quality of the fuel used in the boiler directly affects the thermal efficiency of the boiler. Boiler with good fuel quality can be more fully combusted, thus improving thermal efficiency.
3. Combustion mode: reasonable combustion mode can make the fuel to be more fully utilized, thereby improving thermal efficiency. At the same time, the combustion method will also affect the emissions of exhaust gases, such as nitrogen oxides, carbon dioxide and so on.
4. Exhaust temperature: high exhaust temperature will lead to a large loss of heat, thereby reducing the thermal efficiency of the boiler. Therefore, in the process of boiler exhaust design to reduce the exhaust temperature as much as possible.

In order to improve the thermal efficiency of the boiler, it is necessary to consider and improve from many aspects. Specific methods are as follows:

1. 
   Improve the boiler structure: the improvement of the boiler structure can reduce heat loss, improve combustion efficiency, thereby improving thermal efficiency. For example, increase the heating area of the boiler, the use of advanced combustion technology.
2. 
   2. Improve combustion efficiency: combustion efficiency is one of the main factors affecting the thermal efficiency of the boiler. Can improve combustion conditions, optimize the combustion process, improve fuel quality and other methods to improve combustion efficiency.
3. 
   3. Reduce the exhaust temperature: reduce the exhaust temperature is one of the effective ways to improve the thermal efficiency of the boiler. It can be realized by increasing the waste heat recovery equipment, improving the combustion conditions, improving the flue gas circulation system and so on.
4. 
   4. Optimize flue gas treatment: flue gas contains a large number of harmful substances, the use of effective flue gas treatment technology can reduce emissions and protect the environment.
5. 
   5. Regular maintenance: boiler maintenance is also very critical to improve the thermal efficiency of the boiler. Regular cleaning of the boiler and its components, replacement of aging parts, check the explosion-proof safety measures are to maintain stable operation of the boiler, improve the thermal efficiency of the guarantee
