The engineers at Energy Kinetics created the world's most energy efficient gas boiler by identifying and fixing flaws and inefficiencies in traditional condensing and conventional gas boilers.. Homeowners enjoy our boilers because they are reliable, produce more hot water, last longer, and save them up to 40% on energy costs when upgrading from cast iron models.

Troubleshooting a Gas-Fired Hot Water Boiler

Line up the main burner fuel train with the first MSOV (1) open and the second MSOV (8) closed and line up the pilot fuel train with the MSOV (A) open. This allows testing of all components under actual fuel pressure without firing the main burner. Start up the burner and observe the pre-purge time.

of VOC species in the natural gas fuel (e.g., formaldehyde and benzene) may also contribute to VOC emissions if they are not completely combusted in the boiler. Sulfur Oxides - Emissions of SO2 from natural gas-fired boilers are low because pipeline quality natural gas typically has sulfur levels of 2,000 grains per million cubic feet.

High Efficiency Residential Gas Boilers | Energy Kinetics

A boiler operates for 8,000 hours per year and annually consumes 500,000 million Btu (MMBtu) of natural gas while producing 45,000 lb/hour of 150-psig steam. Stack gas measurements indicate an excess air level of 44.9% with a flue gas minus combustion air temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1).

Jun 18, 2008 · A valve opens, gas enters a sealed combustion chamber in the boiler through lots of small jets, and an electric ignition system sets them alight. The gas jets play onto a heat exchanger connected to a pipe carrying cold water. The heat exchanger takes the heat energy from the gas jets and heats the water to something like 60°C (140°F).
