How to calculate the gas consumption of a gas steam boiler?

Air consumption is an important indicator for evaluating the quality of gas-fired boilers. It is also one of the standards that users measure when purchasing boilers. This data will directly determine the cost of the company's investment in boiler operation.

 

We use a 1 ton gas-fired steam boiler as the base to calculate the method for calculating the gas consumption of the boiler.

First, factors affecting the gas consumption of the boiler
       1. Boiler heating area
       Generally speaking, the larger the heating area is occupied in the whole boiler, the more heat is transferred to the boiler by the fuel combustion, and the fuel utilization rate is improved. On the one hand, the company saves more fuel.
       2. Fuel calorific value and price
       The calorific value of different types of fuels will also vary. The calorific value of natural gas combustion is 8600 kcal/m3, and the calorific value of diesel is 10240 kcal/kg. However, the cost of fuel should also be considered. comprehensive.
       3. Boiler thermal efficiency
       The thermal efficiency of the boiler is also closely related to the heating area. The larger the heating area, the better the heat transfer effect, which will increase the boiler thermal efficiency linearly, make the fuel utilization more complete, and the gas consumption cost less.
       The condensing gas steam boiler produced by Fangfang uses a advanced condensation technology to set up a condensing recovery device near the flue. When the high-temperature flue gas passes through the device, the latent heat part encounters the condensed water to release heat, which is supplied to the boiler for absorption again. The thermal efficiency can be It is as high as 108%. In one year, it can save the company the fuel input cost of 50,000 to tens of thousands (depending on boiler capacity and maintenance quality).
       4, boiler output
       The output of a 1 ton boiler is 700,000 kcal, and so on. The output of a 10 ton boiler is 7 million kcal.

Second, the fuel consumption calculation formula
       Fuel consumption = boiler output ÷ fuel calorific value ÷ boiler thermal efficiency.

According to the above method, the user can calculate the gas consumption of the gas steam boiler according to the various values ​​provided by the boiler manufacturer, and more comprehensively understand the boiler and select the boiler equipment suitable for the enterprise.
