conversion of boiler thermal power and rated evaporation

boiler rating - David Darling

To convert boiler horsepower (hp) into lb. of steam multiply hp × 34.5. Maximum continuous rating is the hourly evaporation that can be maintained for 24 hours. When a boiler operates at its maximum rated capacity it is referred to as maximum load. If the

What is types and price of a 7MW (10 tons) gas boiler ...

Jan 30 2019 · 7MW gas boiler means the rated thermal power of the boiler is 7MW. Generally customer consults 10 ton gas heating boiler about what types and quotations.10 tons generally means the evaporation is 10 tons usually this boiler is called steam boiler. Conversion between megawatts and tons: 1 steam ton = 0.7 megawatts then 7 mw = 10 steam tons.

Boiler Efficiency

dT = temperature difference between inlet and outlet of the boiler (o C) For a steam boiler the heat exported as evaporated water at saturation temperature can be expressed as: q = (m / t) h e (3) where. m = mass flow of evaporated water (kg) t = time (s) h e = evaporation energy in the steam at the saturation pressure the boiler is running (kJ/kg)
