How much heating area can 8 tons gas hot water boiler meet?

Time : 2021-06-02

For users who need to use gas hot water boilers for heating, it is very important to choose the appropriate tonnage of hot water boilers according to the actual size of their own plant heating area. The mismatch of boiler types is likely to cause users to be unable to use normally and cause a waste of resources.

 

Zhengzhou Fangkuai Boiler Factory to 8 tons of gas hot water boiler as an example, for everyone to explain how much this kind of boiler can meet the heating area.The 8-ton gas-fired hot water boiler launched by zhengzhou fangkuai boiler plant uses natural gas as fuel, and the overall operating efficiency is more than 98%, which is well-deserved energy saving and environmental protection equipment.This kind of boiler can meet the heating area of more than 60,000 square meters at the same time.

 

Zhengzhou Fang Kuai Boiler Factory also reminds you that the gas hot water boiler in the hot state of the start of the main steam temperature is lower than the rated value, the specific reasons also see below.

 

For the boiler itself, hot start is actually a certain stage of the whole process of cold start as the starting point.When the unit is out of operation, the boiler cools much faster than the steam turbine.If the steam turbine is hot, or hot, boiler may have cold, so that the boiler start-up operation basically by cold to heat up, booster, as far as possible to meet the hot steam turbine under the transfer request parameters, need to put in more fuel, but only on the bypass system and exhaust steam of steam into the air is not enough, the steam temperature rise faster, and the wall temperature is high.In addition, due to the larger width of the combustion chamber and outlet flue, the temperature distribution in the furnace is uneven, and the steam flow velocity in the superheater serpentine tube is also uneven, and the temperature difference is large, resulting in local overtemperature in the superheater tube.In order to avoid overtemperature of superheater and prolong its service life, it is required that the main steam temperature should be lower than the rated value of 50 ~ 60℃ in the starting process.
