Industrial gas steam boiler is mainly used in industrial production, in chemical industry, food, building materials, textiles, printing and dyeing, clothing and other lines need to use steam as a heat source, that is, need to use steam boiler.
Before purchasing a boiler, many customers are very concerned about the operating cost of the boiler, because it is related to the investment cost of the whole later period. As for the operating cost of gas-fired steam boilers, the operating cost of boilers of different tonnage is different. The following is an example of a 1 ton gas-fired steam boiler to calculate the operating cost of gas-fired steam boilers.
First of all, the operating cost of the industrial gas steam boiler includes fuel cost, water cost, electricity cost, labor cost and maintenance cost. Among them, fuel cost accounts for the highest proportion. At the same time, the price of natural gas and LNG liquefied gas varies from place to place. The following calculation data is a theoretical value, which can be calculated in combination with the actual situation.
Fuel cost: it is necessary to first calculate the gas consumption of the gas-fired boiler. The thermal efficiency of the gas-fired steam boiler is above 95% and the calorific value of natural gas is 8,500 calories. Gas consumption of a 1 ton gas-fired boiler = boiler heat /(calorific value of natural gas * boiler thermal efficiency)= 600,000 CAL /(8,500 CAL 0.95)=74m /h The gas price of natural gas varies from region to region. We take 3 yuan/square, fuel cost =743=222 yuan /h, the operating cost of a 1 ton gas-fired steam boiler for one hour, and the operating cost of one day, one month and one year can be calculated. All localities may conduct accounting according to their prices and market conditions.
From the above, we can see that in the operation cost of industrial gas steam boiler, the largest expense item is fuel cost, and the influence of gas consumption is the boiler thermal efficiency. Therefore, in order to save the investment cost in the later period, when purchasing the boiler, we should choose the gas boiler with high thermal efficiency.
