Many people have such questions when choosing 20 Tons Steam Boiler, Is 20 Tons Coal Fired Steam Boiler or 20 Tons Gas Steam Boiler Good? In view of this problem, we might as well look at the advantages of the two.

Advantages and disadvantages of 20-ton coal-fired steam boiler

Advantages: less upfront investment, relatively low equipment price, and lower operating cost than gas-steam boilers in the short term.

Disadvantages: serious pollution, low degree of automation, need manual control, need to invest some labor costs.

Advantages and Disadvantages of 20 Ton Gas Steam Boiler

Advantages: clean fuel, high degree of automation, can save labor costs.

Disadvantages: expensive equipment, large upfront investment, unfriendly to start-up enterprises with a shortage of capital budget.

In summary:

Although the country has been advocating green industry, reducing emissions, and punishing and rectifying some enterprises that do not meet the emission standards, in a short period of time, natural gas energy still cannot replace coal energy as the main fuel for enterprise development. However, in the long run, it is the general trend that natural gas replaces coal to become cleaner energy. Therefore, enterprise development will depend on natural gas energy transformation sooner or later.
