Dec 15, 2017 · For natural gas boilers, the hydrogen content of the raw fuel is high, and the latent heat usually occupies a large proportion of the total waste heat, . The technologies based on condensing heat exchangers recover heat by cooling the flue gas under its dew point with extra cooling medium, thus the final state of the flue gas is limited by the temperature of cooling medium.
is of most importance, especially to waste wood. Natural gas and most oil fuels are referred to as "clean burning" fuels primarily due to their lower tendency to form solid combustibles, such as smoke, soot, and carbon, and their low ash content. On the other hand, waste wood boilers produce particulate matter to some degree. Air pollution
Basic Information about Landfill Gas | Landfill Methane
Jan 01, 2016 · It is planned that the heating area is 4.8 billion square meters by natural gas boiler until 2015 in Beijing, the Potential of the waste heat of the gas boiler can replace 0.48 billion square meters heating area. That is, there are about 1 billion square meters heating area which could be solved by waste …
Fewer Emissions – Combustion of natural gas, used in the generation of electricity, industrial boilers, and other applications, emits lower levels of NOx, CO2, and particulate emissions, and virtually no SO2 and mercury emissions. Natural gas can be used in place of, or in addition to, other fossil fuels, including coal, oil, or petroleum coke, which emit significantly higher levels of these pollutants.

by "surplus" hydrogen and natural gas. Hydrogen is produced on site as a bi-product of the chlor-alkali process. Surplus hydrogen which is either not sold to customers or used within the process is used as fuel. Boiler efficiency, or fuel-to-steam efficiency, represents the difference between the energy input (fuel) and energy output (steam).
Increasing Natural Gas Boiler Efficiency by Capturing
Landfill gas (LFG) is generated by the natural degradation of MSW by anaerobic (without oxygen) micro-organisms. Once the gas is produced, the gas can be collected by a collection system, which typically consists of a series of wells drilled into the landfill and connected by a plastic piping system.
