Consider Installing High-Pressure Boilers with

When specifying a new boiler, consider a high-pressure boiler with a backpressure steam turbine-generator placed between the boiler and the steam distribution network. A turbine-generator can often produce enough electricity to justify the capital cost of purchasing the higher-pressure boiler and the turbine-generator.

Steam Pressure Reduction: Opportunities and Issues

Steam Pressure Reduction: Opportunities and Issues varies directly in proportion to the boiler's net stack temperature (the difference between the flue gas tem-perature and combustion air temperature). When boiler pressure is lowered, a lower stack temperature results. This, in turn, causes slightly improved combustion efficiency.

is high efficiency gas boiler worth the investment? what's

A high efficiency gas boiler (>90%) must have the flue gas condense in order to achieve that efficiency. The flue gas will only condense when the return water temperature is 120 degrees or less. An ordinary system has return water temperature much higher than this, because this is the temperature for which your radiators are sized (typically

High Pressure vs. Low Pressure Boiler

Nov 23, 2011· Difference Between a High Pressure and Low Pressure Boiler. (The measurement psi is used to determine pressure, and stands for pounds per square inch.) By definition, a high pressure boiler is one that operates above 15 psi, while a low pressure boiler is one that operates at 15 psi or lower.

Boiler Introduction | CleanBoiler.org

General Boiler Information. 1 boiler horse power is about 42,000 BTUs of INPUT. 1 pound of steam is about 1,200 BTUs of INPUT fuel, and about 1,000 BTUs at the point of use, depending on the pressure of the steam. Low pressure steam is considered to be up to 15 psi; high is generally 100 psi and higher.

High Pressure Boilers - Industrial boilers

The greater the difference between the temperature of the rising steam and the temperature of the steam when it leaves the boiler, the higher efficiency will be achieved. High pressure boilers use water-tubes because a normal fire-tube could not produce high enough temperatures or pressures even if it was bigger, stronger and fed more fuel.

Why you can't use high-pressure steam boilers on low

Jun 23, 2014· This is why you can't run a high-pressure boiler on low-pressure settings. The boiler manufacturer told the contractor about this when the contractor called to ask. The contractor thought he could get around the high-velocity problem by cutting into the boiler and welding a bigger nozzle onto the shell. The boiler manufacturer said this would probably work, but the contractor hadn't mentioned the
