In most cases ten minutes of water should be readily available for your boiler. One boiler horsepower = 34.5 lbs/hr of steam (or water) from and at 212o F. We also know that one-gallon of water weighs 8.37 lbs. To calculate the storage tank needed use the following formula: BHP X 34.5 ÷ 8.337 lbs ÷ 60 min. X 10 = minimum useable capacity in

Water/Steam Injection. Water or steam injection can be utilized to reduce NOx levels. By injecting water or steam into the flame, flame temperatures are reduced, thereby lowering thermal NOx formation and overall NOx levels. Water or steam injection can reduce NOx up to 80% (when firing natural gas) and can result in lower reductions when

low-pressure steam or hot water, and are most commonly used in small commercial applications. Natural gas is also combusted in residential boilers and furnaces. Residential boilers and furnaces generally resemble firetube boilers with flue gas traveling through several channels or tubes with water or air circulated outside the channels or tubes.

When steam demand from the plant is low, and the boiler is capable of generating more steam than is required, the surplus steam is injected into a mass of water stored under pressure. Over a period of time the stored water content will increase in temperature and pressure until it finally achieves the saturation temperature for the pressure at

Steam boilers benefit from vent dampers more than hot-water boilers, and larger boilers benefit more than smaller ones. Vent dampers, however, may not be cost-effective with properly sized, newer furnace models. For older oil burners, converting to a flame retention burner is probably a better investment.

Hot Water Boiler Piping Zone Valves - Boiler piping zone valves are used for zoning hot water systems where multiple zones are needed.Hot water system zoning can also reduce energy cost because hot water heat zones which are not needed can be shut down thereby reducing boiler runtime to provide hot water heat for those specific zones.. Zoning a hot water boiler system can be done by using
