Direct-vent boilers offer the best efficiency. If you have an older boiler, it will have a metal flue that is connected to a chimney.This type of boiler relies on natural "atmospheric" combustion. In contrast, a gas-fired, direct-vent boiler is designed to extract more heat from a given quantity of fuel.
Boilers are fueled by natural gas, heating oil, propane, electricity or a biodiesel-oil blend. New systems are very energy efficient, with efficiencies as high as 98.5 percent. What Type of Boiler
What is the thermal efficiency of gas fired steam boilers 2018-12-25 Generally speaking, not only gas fired boiler, including oil fired boiler, WNS oil fired gas boiler and SZS oil fired gas boiler can achieve at least 95% thermal efficiency.
It consists of two high-performance natural gas boilers working in cascade, with adjustable useful power between 320 and 500 kW each and 92.7% energy efficiency at full load and 95.2% when the load is 30%.
Most industrial and commercial users of packaged boilers now fire natural gas. You'll find #2 oil commonly used as a back-up fuel for hospitals and industry, and in some geographic areas without natural gas service. This information is intended for use by the vast majority that fire natural gas and also touches on #2 oil.
Boilers use natural gas, oil, electricity, propane, or wood to create hot water or steam that heats your home through radiators, baseboard convectors, radiant floors, or fan-forced coils.
Boiler burners are the functional component of boilers that provide the heat input by combustion of a fossil fuel, including natural gas, with air or oxygen. They are available either as part of the boiler package from the manufacturer, as stand-alone products for custom installations, or as replacement products.
To produce one ton of steam, You need 666000 kcal. To produce one ton of steam, and every one m3 of gas gives 9520 kcal. So, around 69 m3 of gas will produce 1 ton of steam. In case of fuel & air and no scales in the boiler. Also by increasing

Using the same combustion gas analysers, most high efficiency boilers are about 90% gross efficient (10% of your money is wasted). Changing from a reasonable, old, room-sealed boiler to a new high efficiency boiler will save you about 10% - 15% of the money you spend on gas. Figures claiming savings of 30% or more seem not be be physics but magic.

Heat sources. In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas.In some cases byproduct fuel such as the carbon-monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.. In a nuclear power plant, boilers called
since natural gas contains no Particulate Matter (PM), the PM emissions are virtually zero other than "background" PM present in the combustion airflow or that which is swept from the boiler. Regarding NOx, natural gas contains low fuel-bound nitrogen content and requires lower excess air for
