SZS35-2.45/350-Q gas steam boiler size, gas consumption

Question details (performance) :

The SZS35-2.45/350-Q gas steam boiler is a 35 ton steam furnace, also known as a 35 ton gas furnace. The 35-ton gas-fired boiler has a rated pressure of 2.45 MPa, which is a special type of boiler in special equipment boilers. The operating weight is 58 kg and the external dimensions are 12370*4280*4210. The detailed technical parameters are as follows:

Boiler model: SZS35-2.45/350-Q;

Rated evaporation of 35t / h;

Rated working pressure 2.45Mpa;

Feed water temperature 350 ° C;

The outlet steam temperature is 90 ° C;

Boiler water capacity 2.5m3;

Boiler design efficiency (gas) 95%;

Boiler design efficiency (oil) 94%;

What is the air consumption of the SZS35-2.45/350-Q gas steam boiler?

Gas steam boiler gas consumption calculation formula: gas steam boiler 1 hour gas consumption = gas boiler power * 3600s / fuel calorific value / thermal efficiency. We know how much gas is consumed by the SZS35-2.45/350-Q gas steam boiler?

The conversion rate of 35 steam tons is 24.5MW, and 1 hour is equal to 3600s. The calorific value of natural gas is generally between 35.88 MJ/M3-39.82 MJ/M3, and we take a median of 37 MJ/M3. The thermal efficiency of gas boilers produced by Zhengguo can reach 92%. Then you can get the formula by nesting:

Gas consumption of SZS35-2.45/350-Q fuel gas boiler: 24.5MW*3600S/37MJ/92%=2591M3/h.
