Difference between direct-fired engine and gas-fired boiler

Principle, operation mechanism, application field and environmental protection.

1, principle and operation mechanism: Direct-fired engine is a new type of equipment with high combustion efficiency. The combustion mode is that gas is directly injected into the combustion chamber, and then mixed with air to generate high-temperature and high-pressure gas, and then water or air is heated. Gas-fired boiler is a traditional heating equipment. Its main principle is to send gas into the combustion chamber for combustion, heat water through the heat generated by combustion, and then generate steam for external heating.

2. Application field: Direct-fired engine has the advantages of fast temperature rise, wide temperature adjustment range and small volume. High heating efficiency, can provide a lot of heat energy in a short time. It is suitable for heating workshops, parking lots, commercial complexes, stadiums and other public places, and can also be used in industries such as hot air drying and printing heating. Gas boilers are widely used in small and medium-sized enterprises and individual families because of their stable, mature and reliable structure.

3. Environmental protection: Due to its special combustion mode, the direct-fired engine can effectively use gas and reduce energy consumption and cost. The waste gas produced by gas boiler combustion must be treated specially before it can be discharged, otherwise it may cause pollution to the environment.
