Comparison of cost between electric heating hot water boiler oil-fired heating hot water boiler and
Due to the serious environmental pollution caused by coal-fired heating hot water boilers, all cities in China have strictly prohibited the installation and use of coal-fired heating hot water boilers in urban areas, and rectified the coal-fired heating hot water boilers stored in them within a time limit. Heating hot water boiler users can only choose other fuel environmental protection heating hot water boiler, so what fuel heating hot water boiler is the most suitable?
Next, we compare the operation of electric heating hot water boiler, fuel heating hot water boiler and gas heating hot water boiler. The calorific value of natural gas is 8600KCalN / km, the calorific value of diesel oil is 9600KCalKG, and the calorific value of electricity is 860KCal/ kilowatt-hour. In general, the thermal efficiency of oil-fired hot water boiler and gas-fired hot water boiler is about 95%. The thermal efficiency of electric heating hot water boiler is about 99%. Take 100000 kcal heating hot water boiler as an example, if diesel fuel is burned, the consumption is 10.96kg / h, and the price of diesel oil is 8 yuan / Kg, per hour. The cost is 87.68 yuan, and if the natural gas is burned, the consumption is 12Nm / h, and the price of natural gas is 45.6 yuan per hour at the price of 3.8yuan / Nm,.
If the electric heating hot water boiler is selected, the consumption is 120kW / h, and when the power price is 1 yuan / kilowatt / span >, the cost per hour is 120 yuan. By comparison, the operation cost of electric heating hot water boiler is the highest, the operation cost of gas heating hot water boiler is the lowest, and the operation cost of fuel heating hot water boiler is in the middle. It is very correct to choose gas heating and hot water boiler where there is gas pipeline.
