Average Cost of a New Boiler

In the industrial boiler industry, commonly used boilers can be divided into coal-fired boilers, gas-fired boilers, oil-fired boilers, biomass boilers, and electric heating boilers according to the fuel used. Boiler cost is our most concerned point. Understanding the operation of various fuels the cost can reduce the operating cost of the boiler, thereby increasing the economic benefits of the enterprise.

 

 

Take the cost of heating 50 tons of 42 ° C hot water as an example:

1 kilogram of water needs 1 kcal of heat to heat 1 degree. This calculation is based on 10 degrees of tap water: 42-10 = 32 degrees (Δ = 32 degrees) to warm to 42 degrees. 50 tons of water = 50000 kilograms and 1 degree = 50000. X 1 kcal = 50000 kcal heating up 32 degrees = 50000 kcal X 32 = 1600000 kcal.

1. Coal-fired Boiler

The calorific value of standard coal for coal-fired boilers is 5000 kcal / kg. Based on the coal price of each place, the average value is 1.6 million kcal ÷ 5000 kcal X 1.2 yuan = 384 yuan. The thermal efficiency of coal fired boilers is generally 384 ÷ 0.8 = 480 yuan.

2. Biomass Boiler

The calorific value of biomass particles on the market is 4000 kcal / kg. According to the biomass particles in each place, it is calculated at 1 yuan per kilogram. 1600 kcal ÷ 4000 kcal X 1 yuan = 400 yuan. The thermal efficiency of biomass boilers is generally 400 ÷ 0.8 = 500 yuan.

3. Gas Boiler

The calorific value of natural gas is 8600 kcal / m3. Based on the average price of natural gas in each place, the average value is 3.5 yuan per cubic meter. Calculated at 1.6 million kcal ÷ 8600 kcal X 3.5 yuan = 651 yuan. The thermal efficiency of gas boilers is generally 90% ÷ 0.9 = 723 yuan.

4. Oil-fired Boiler

The calorific value of diesel is 9600 kcal / kg. According to the current price of diesel, it is calculated at 7.6 yuan per kilogram at 1.6 million kcal ÷ 9600 kcal X 7.6 yuan = 1266 yuan. The thermal efficiency of oil-fired boilers is generally 90%, 12600 ÷ 0.9=1407 yuan.

5. Electric Boiler

Calorific value of electricity: 860 kcal / KW, according to industrial electricity standards, the price of electricity are calculated at 1.0 yuan / degree. 600000 kcal ÷ 860 kcal X 1 yuan = 1860 yuan, the thermal efficiency of electric heating boilers is generally 98%, 1860 ÷ 0.98 = 1898 yuan.

 

 

According to the above data, the operating costs of heating 50 tons of 42-degree hot water for bathing with various fuels are: RMB 480 for coal-fired boilers, RMB 500 for biomass boilers, RMB 723 for gas boilers, RMB 1407 for oil-fired boilers, and RMB 1898 for electric heating boilers.
