Steam Pressure Reduction: Opportunities and Issues

2013-9-26 · 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.

10 Tips to Optimize Your Steam-Injection Heating

Steam-injection heating can come online quickly, which makes it suitable for intermittent heating requirements. Keep in mind though, that when heating is called for, the heater will move to the fully open position. If the heater's steam demand is close to the boiler's available output, this can draw down your boiler faster than desired.
