20t / h coal-fired boiler model specification recommendation and coal consumption calculation

The coal consumption of a 20t / h Coal-Fired Boiler is about 2700 kg / h. This is the assumption that the efficiency of a 20-ton boiler is 80%. If the thermal efficiency is increased, the boiler coal consumption will be greatly reduced. The calculation of coal consumption for coal-fired boilers can be viewed directly at https://www.zhongzhengguolu.cn/faq/faq-635.html.

At present, the provinces and cities of the country have implemented policies to ban and dismantle small coal-fired boilers under 10 tons. Some provinces and cities have reached the limit of 20 tons of coal-fired boilers and equipment below. In other words, some provinces and cities are not allowed to build coal-fired boilers under 20 tons, but many remote provinces and cities still allow the use of coal-fired boilers of this capacity. Therefore, if you want to purchase a 20t / h coal-fired industrial boiler, then you must determine the relevant environmental protection policies in your area. For this, you can also directly consult online. Zhongzheng boiler customer service staff will answer your questions.
