Which is more energy-efficient and cost-effective, electric steam generator or gas steam generator
Generally speaking, under the premise of the same evaporation capacity, although the purchase price of electric heating steam generator equipment is cheap, the operating cost of gas steam generator is relatively low. The cost of using natural gas is one-third of electricity (in the case of electricity cost of 1 yuan per kilowatt hour). If the equipment works for a long time and consumes a large amount of steam, it can be said that choosing a gas steam generator is more cost-effective.
According to data, a 1-ton electric heating steam generator consumes 720 kWh of electricity per hour, and a 2-ton electric heating steam generator consumes 2 * 720=1440 kWh of electricity per hour. If industrial electricity is calculated at 1 yuan per hour, the operating cost of a 2-ton inspection free electric heating steam generator is 1440 yuan per hour.
A 2-ton gas generator consumes 150-160 cubic meters of natural gas per hour, calculated at 3 yuan per cubic meter (prices vary in different regions). The operating cost of a 2-ton gas generator per hour is 150 * 3=450 yuan.
So, from an economic perspective, gas steam generators are more energy-efficient, have lower operating costs, and generally meet conventional production needs than electric steam generators.
Compared to gas steam generators, electric heating steam generators have much higher thermal efficiency. Resistance heating elements can directly transfer heat to water, achieving high thermal conversion rates and improving thermal efficiency, which is also a way to reduce fuel consumption. Moreover, electricity is a clean energy source, eliminating the need for energy-saving devices and emission sensors, which can reduce purchasing and usage costs.
We also need to consider a situation where, when a steam equipment is used in a location with strict requirements for pollution emissions, even if we want to choose a gas steam generator at this time, it is not possible. After all, environmental issues may arise in the later stage, and even increase the cost of use.
So, it cannot be directly determined whether an electric steam generator or a gas steam generator is cost-effective. Environmental protection, electricity costs, steam demand, equipment usage frequency, and other factors are all conditions that we need to refer to.
