As a common industrial boiler, coal-fired boilers have always been the preferred targets of many users. Bituminous coal, biomass, wood, corn stalks, palm husks, etc. can be used as boiler fuel. From the point of view of efficiency, the combustion efficiency of bituminous coal is the highest.
Therefore, users are also very concerned about the fuel consumption of such boilers. Here, we will give the calculation formula of boiler consumption and the consumption of common boilers, so that customers can refer to it when selecting models.
So, we list a reliable formula during boiler fuel consumption calculation. Meanwhile, a combustion efficiency chart is given in this article.
1. Boiler Fuel Consumption Calculation Formula
The boiler fuel consumption chart is below.
Here C is recorded as the consumption, H as the rated calories of the boiler, V as the burning value of coal, E as the thermal efficiency of coal steam boiler.
C=H/V/E
For example：
1T coal steam boiler for sale needs 600,000Kcal/h, let us suppose the lowest burning value of coal is 5,500Kcal/kg, and the thermal efficiency of a 1 ton boiler fuel consumption is about 80%(the highest efficiency of boiler from Yongxing is about 90%), then according to the boiler efficiency formula:
C=H/V/E
=60000/5500/80%
=136kg/h
2. Boiler Fuel Consumption Calculation Note
In fact, there are many factors affecting the boiler fuel consumption calculation, such as the service life of the boiler, the use occasion, the boiler structure, the local altitude, the coal combustion efficiency, and the load.
The above formula can provide a reference for users when selecting models, and the specific consumption should be determined according to the actual situation.
All data and formulas come from our company’s laboratory.
3. Boiler Fuel Consumption Calculation Reference Table
The boiler fuel consumption calculation xls is as follows. We list the boiler fuel consumption calculation from 1t/h to 100t/h of steam boiler
