With the development of customers, when choosing industrial boilers, they also attach great importance to energy conservation and environmental protection, and can also effectively control the cost of new boilers. The operating cost of biomass boilers in Kenya. This article starts with biomass boilers and analyzes the operating costs of different fuels.
Industrial boilers are classified according to the fuel used and can be divided into oil and gas boilers, coal-fired boilers, biomass-fired boilers, organic heat carrier boilers, and electric heating boilers; fully understand the operating costs of different fuels and can effectively control the operation of a new boiler Cost in turn increases the economic benefits of the enterprise. This is a factor that must be considered when choosing a boiler.
Take 50 tons of hot water at 42 ° C as an example:
One kilogram of water needs 1 kcal to heat up 1 degree. This calculation is based on 10 degrees of tap water: 42-10 = 32 degrees to warm up to 42 degrees, 50 tons of water = 50000 kilograms and 1 degree of heat = 50000 X 1 kcal = 50000 kcal heating up 32 degrees = 50000 kcal X 32 = kcal.
1. Fuel oil boiler
The calorific value of diesel is 9600 kcal / kg. According to the current diesel price per kilogram, 7.6 kcal ÷ 9600 kcal X 7.6 yuan = 1266 yuan. The thermal efficiency of oil-fired boilers is generally 90%, 1266 ÷ 0.9 = 1407 yuan.
The calorific value of natural gas is 8600 kcal / m3. Based on the average price of natural gas in various places, the caloric value is calculated at 3.5 yuan per cubic meter ÷ 8600 kcal X 3.5 yuan = 651 yuan. The thermal efficiency of gas boilers is generally 90%, 651 ÷ 0.9 = 723 yuan.
2. Biomass boiler
The caloric value of biomass particles on the market is 4000 kcal / kg. According to the biomass particles in each place, the calorie is calculated at 1 yuan per kilogram ÷ 4000 kcal X 1 yuan = 400 yuan. The thermal efficiency of biomass boilers is generally 80 @ 0 ÷ 0.8 = 500 yuan.
3. Coal-fired boilers
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 1.2 yuan per kilogram. 5000 kcal X 1.2 yuan = 384 yuan, the thermal efficiency of coal-fired boilers is generally 8084 ÷ 0.8 = 480 yuan.
4. Electric heating 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.
Therefore, the operating costs of heating 50 tons of 42-degree hot water are: RMB 723 for gas boilers, RMB 1407 for oil boilers, RMB 500 for biomass boilers, RMB 480 for coal-fired boilers, and RMB 1898 for electric heating boilers. It is not difficult to see that biomass-fired boilers are economical and practical. Buying a boiler can be based on the project situation to select the most suitable boiler.
