Gas-fired hot water boiler is a kind of thermal energy equipment that uses natural gas, biogas, etc. as fuel to heat water to a rated temperature. Gas-fired hot water boilers are mainly used for heating and bathing, and can be used for heating, bathing and domestic hot water in hotels, schools, guesthouses, communities and other enterprises and institutions. With the promotion of the "coal-to-gas" policy, gas-fired hot water boilers have become more widespread.

1. Rated thermal power

　　Rated heating power refers to the hourly heating capacity of a gas-fired hot water boiler, which is closely related to the heating area. The heating area of ​​the six-ton ​​gas-fired hot water boiler is 36000-48000 square meters.

2. Rated working pressure

　　Pressure P, the unit is Mpa. The rated working pressure refers to the boiler pressure that must be guaranteed for long-term continuous operation of a six-ton ​​gas-fired hot water boiler under the specified boiler thermal efficiency, feed water temperature and target hot water temperature, which is the pressure indicated on the boiler nameplate.

3. Temperature of inlet and outlet

　　The feed water temperature refers to the temperature of the water as the working fluid when it enters the steam boiler. The rated feed water temperature is the feed water temperature that should be guaranteed within the specified compliance range. Zhongzheng gas-fired steam boilers are equipped with flue gas recovery devices such as economizer condensers, which can effectively use flue gas temperature to increase the boiler return water temperature and effectively improve the thermal efficiency of the boiler system.

4. Boiler thermal efficiency

　　Boiler thermal efficiency refers to the heat transfer effect of the heat generated by fuel combustion to the water in the boiler. The higher the thermal efficiency, the better the boiler performance. The boiler energy-saving technology supervision and management regulations stipulate that the thermal efficiency of natural gas boilers is 92%, and the thermal efficiency of the six-ton ​​gas-fired hot water boiler produced by Zhongzheng Boiler can reach 95%.

　　In addition, the six-ton ​​gas-fired hot water boiler can be divided into vertical and horizontal according to the structure, and users can choose according to the area of ​​the boiler room.
