Natural gas boilers use natural gas as fuel to heat the heat medium water through the burners, and then exchange heat to provide heating and hot water for living and bathing. Now it has a relatively complete production line, high boiler intelligent degree, fast heating speed, low noise, no dust and other pollutants. It is an economical and environmentally friendly hot-selling boiler product that is very suitable for China's national conditions.
The electric boiler is a boiler device that uses electric energy as an energy source to convert hot water and heat the hot water through electric heat conversion, and has the characteristics of no waste discharge pollution, high degree of automation operation, and no noise.
We calculate the operating costs of both according to the heat required to heat 1 ton of water from 15 ° C to 50 ° C.
A total of heat Q = 1000 kg × (50-15) × 1 kcal / kg ° C = 35000 kcal is required.
First, the operating cost of electric boiler
1 degree electric heat is 860kcal / kWh × thermal efficiency 90% = 774kcal / kWh;
The power consumption of 1 ton of hot water is 35000kcal ÷ 774kcal / kWh = 45.22 degrees;
The electricity price is 0.6 yuan / kWh, then the cost of heating 1 ton of hot water: 45.22 × 0.6 = 27.13 yuan;
Therefore, the operating cost of electric boiler heating 1 ton of hot water is 27.13 yuan.
Second, natural gas boiler operating costs
1m3 natural gas heat is 8500kcal/m3×thermal efficiency 100%=8500kcal/m3;
The gas consumption of 1 ton of hot water is 35000kcal ÷ 8500kcal / m3 = 4.12m3;
The price of industrial natural gas is 2.9 yuan / m3, then the cost per ton of hot water: 4.12 × 2.9 = 11.95 yuan Therefore, the operating cost of heating 1 ton of hot water in a natural gas boiler is 11.95 yuan.
This formula calculates the gas consumption data of the natural gas boiler with a thermal efficiency of 100%. In practical applications, the gas consumption is higher. When calculating the gas consumption of natural gas boilers, the natural gas calorific value and boiler efficiency should be fully considered. The value that comes out can be in line with the actual situation.
