Atmospheric Gas Fired Water Heater/Boiler Operating and
The manifold pressure is measured downstream of the gas pressure regulator. Do not exceed the maximum gas pressure specified on the rating plate. (4) A trap (drip leg) must be installed upstream of the gas pressure regulator. (5) The heater must be disconnected from the gas supply piping system during any pressure testing of the gas supply piping.

Back to Basics: Venting for Gas-Fired Boilers | Liming
Lastly, some boilers have a domestic hot water coil for making hot water for showers, washing dishes, so on and so forth. Sometimes, after prolonged use, a domestic coil inside the boiler jacket can develop a pinhole in the tubing. If this happens, the boiler pressure is affected by pressure from the domestic coil.

why negative pressure is maintained in furnace?
May 03, 2017 · Positive pressure :- When the pressure in combustion area of the boiler is more than atmospheric pressure, normally forced draft boilers, HRSG are positive pressure. Negative pressure :-When the pressure in combustion area of the boiler is less than atmospheric pressure. This is achieved in balanced draft boilers by using Forced draft fans to force air into boiler (pressuring it)and Induced draft fans to remove air from the boilers to create negative pressure.

Biomass Cofiring in Coal-Fired Boilers
Biomass power systems are typically below 50 MW in size, compared to coal-fired plants, which are in the 100- to 1,000-MW range. Most of today's biomass power plants are . direct-fired systems. The biomass fuel is burned in a boiler to produce high-pressure steam that is used to power a steam turbine-driven power generator.
