gas boiler maximum use of steam

Natural Gas Fired Boilers

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).

Efficiency factors in natural gas fired steam boilers

Maximum efficiency is obtained generally when a boiler is used at 65-75% of load. 1 When the load of the boiler falls below 50%, in order to burn all of the fuel, more excess air should be fed and this will increase heat losses. Therefore, a boiler load which is under 50% is not suitable in terms of efficiency. 3.

Boiler Efficiency and Steam Quality: The Challenge of

"Operate the boiler at its maximum design pressure" is a common saying among boiler designers. But too often, this rule is not followed when energy cost reductions are needed. During periods of low steam demand, or when all the use points require pressure-reducing stations, boilers are often operated at substantially less than design pressure.

Plant Engineering | When to use electric steam boilers

The reasonable optimal steam production of Exhaust Gas Boilers where no economizers are incorporated are consequently reached at a steam pressure of 3-4 bar (saturated temperature 143-151°C). In practice it is found that the pinch temperature shall be kept at minimum 25°C as a lower temperature difference will substantially increase the
