agent or sales office. 5. Gas ratings are based on natural gas with heating value of 1,000 Btu per cubic foot and specific gravity of 0.60. 6. Boiler-burner unit must be adjusted to achieve 0.10 inches W.C. pressure at flue collar, resulting in positive pressure in firebox as listed in Table 1. 7.Learn More
that of natural gas. Therefore, the volume of LFG that must be handled by the fuel train and burner is twice that of natural gas. This means that modifications to the fuel train and burner are usually required to accommodate the higher overall gas flowrate for an equivalent natural gas heating value.Learn More
An efficient natural gas burner requires only 2% to 3% excess oxygen, or 10% to 15% excess air in the flue gas, to burn fuel without forming excessive carbon monoxide. Most gas burners exhibit turndown ratios of 10:1 or 12:1 with little or no loss in combustion efficiency. Some burners offer turndowns of 20:1 on oil and up to 35:1 on gas. A higherLearn More
IBC was established in Vancouver, BC with the express purpose of improving the world of hydronic heating. We recognized that innovations in combustion control technology, combined with appropriate design-embedded controls, are fundamental foundations for the optimization of our new, reliable heating equipment both for residential and commercial use.Learn More
Feb 09, 2015 · A direct flame combustion H 2 boiler is functionally identical to the gas boilers installed in Europe and North America to supply residential central heating, except that it burns hydrogen instead of natural gas. Like natural gas boilers, direct combustion of the gas …Learn More

About Condensate Neutralizers Condensate produced by high efficiency condensing equipment, including residential and commercial gas boilers, hot water heaters and furnaces, has inherently low pH (is acidic) and poses a problem for sewer piping and septic systems.Learn More
Most boilers use natural gas, fuel oil, or coal burners to provide heat to the boiler. The key components of natural gas burners include pilots, impellers, spuds, spiders, and igniters. Knockout pots remove liquids and condensate from the fuel gas before it is sent to the burners. Damp-ers regulate the flow of air to the burner. Impellers in Learn More
Gas-Fired Boilers and Furnaces. A residential natural gas meter. Gas boilers and furnaces can be fueled by either natural gas or propane with simple modifications accounting for the different characteristics of the fuels. Propane is usually more expensive as a fuel, but is available throughout the United States.Learn More
NAVIEN BOILERS BENEFITS Conventional Boilers Lose Heat Condensing Boilers Retain It. Save space, energy and reduce greenhouse gasses with Navien high efficiency condensing boilers. Low exhaust gas temperatures allow for more cost-efficient venting, and low …Learn More
reducing nitrogen oxide (NOx) emissions from natural gas-fired industrial and commercial boilers, and boilers can typically operate at recirculation rates of 20-25 percent without adversely affecting boiler heat transfer and efficiency. This comparison illustrates that the increased flow of LFG as compared to natural gas will not adversely affect boiler operation, although the burner, controls, and fuel train will require …Learn More
Boilers are typically between 75% and 96% efficient in the primary process of heating the water, but any un-insulated heating water piping will lower the overall efficiency of space heating. In addition to the boiler unit, a gas-fired boiler requires a feed water supply, a boiler loop/heat delivery system (e.g., hydronic radiators or fan coil Learn More
Feb 27, 2014 · One of the most misunderstood portions of the commercial heating system is the gas train. The gas train is a series of components that safely feed natural or propane gas into the burner. The first component of the gas train is the sediment trap, more commonly referred to as the "dirt leg." This is used to catch any dirt or moisture that may be entrained in the natural gas feed to the building.Learn More
For cast iron boilers the feed water shall not be introduced through openings or connections used for relief, water column, or water level gage glass. NYS Rule 4-13.4 (d), 4-14.4 (b) and 4-5.9. A check valve shall be installed in a city water feed line for steam boilers. NYS Code 4-5.9Learn More
Of course, this never happens, therefore burner combustion air fans may be sized for 25% excess air, in which case the fan would deliver 12.5 ft 3 of air per 1 ft 3 of natural gas. Additionally, many burner manufacturers will size the combustion air fans to provide sufficient air to operate properly up to 2,000 feet in altitude, in which case Learn More

for natural gas fired industrial boilers at <30 PPM NOx. This was achieved with either forced or induced FGR. In the years that followed, some burner suppliers were able to achieve <30 PPM NOx without FGR, See Figure 3 for an example of a gas flame from an industrial low NOx burner on a large watertube boiler operating at <15 PPM with induced FGR.Learn More
