Gas steam generators are more cost-effective than electric steam generators in terms of energy savings.

 
From the purchase cost of equipment for electric steam generator the same evaporation capacity under the premise of electric steam generator price is certainly lower than the gas steam generator, in the purchase and installation cost of electric steam generator is far lower than the gas steam generator. But the cost of gas steam generator that the cost of energy is far lower than the electric steam generator.
Data show that 1 ton of electrically heated steam generator consumes 720 degrees of electricity per hour, 2 tons of electrically heated steam generator consumes 2 * 720 = 1440 degrees of electricity per hour, industrial electricity per hour in accordance with the calculation of 1 yuan, then, 2 tons of exempted from the inspection of electrically heated steam generator is 1440 yuan per hour of operating costs.
2 tons of gas generator hourly consumption of 150 - 160 cubic meters of natural gas, according to the calculation of 3 yuan per cubic meter (each place price is different), 2 tons of gas generator hourly operating cost of 150 * 3 = 450 yuan.
Gas steam generators are definitely more cost-effective than electric steam generators for long-term large evaporation.
