Minimum operating Gas Pressure on boiler | Screwfix

Typical pressure for a residential boiler serving a two story home would show 12 psi cold, and less than 30 psi hot. Over 30 psi boiler pressure will cause the pressure relief valve to open. Typical hydronic heating boiler operating temperature settings are LO-120-160 HI-180-200 °F. At 200 °F. we'll see should see pressure under 30 psi.

Ideally, when the boiler is on, the pressure should be between 1,5 to 2 bars, and when it's not working – 1 to 1.5 bars. Usually, safe levels of the pressure are marked in green, and too low or too high-pressure is marked in red. We consider high boiler pressure when the arrow points in the red zone exceeding 2 bars.

Effects of space heating on the pollutant emission

May 15, 2020 · The results for coal-fired boilers show that the pollutant emission concentration is generally higher for small coal-fired boilers below 20 t/h due to limitations of the desulfurization equipment . SO 2 emission per unit of flue gas from a small boiler can be 2 to 3 times larger than that in a large coal-fired boiler above 80 t/h, and soot emission can be 8 to 10 times larger.
