May 15, 2015 · boiler. 3. GAS PRESSURE REQUIREMENTS The AERCO AM Series of boilers and water heaters require a stable gas input pressure. The inlet supply to the unit must be at least 3 W.C. when firing at maximum input. Maximum allowable gas pressure is 13 W.C. Static gas pressure (when the unit is not firing) may vary, however actual gas

The fire tubes shall be 1/2 or 5/8 OD, with no less than 0.049 wall thickness. The upper and lower stainless steel tubesheet shall be no less than 0.25 thick. The pressure vessel/heat exchanger shall be welded construction. The heat exchanger shall be ASME stamped for a working pressure not less than 150 psig.
The CCS determines how much fuel, air, and water to put into the boiler, and should prevent unsafe conditions from happening in the first place. This article does not cover the BMS, well focus primarily on the fuel and air aspects of the CCS (rather than water and other auxiliary components).
1.4 Natural Gas Combustion 1.4.1 General1-2 Natural gas is one of the major combustion fuels used throughout the country. It is mainly used to generate industrial and utility electric power, produce industrial process steam and heat, and heat residential and commercial space. Natural gas consists of a high percentage of methane (generally above
In the early 1900s as boiler codes and rules were being established, it was decided that a high pressure boiler would be 15 PSI and above, with anything lower being defined as a low pressure boiler. The industry has maintained this standard for over a hundred years and boiler regulations and standards have been built around it.
