boiler exhaust gas

Is a high efficiency, condensing gas boiler the best

Condensing boilers cool the exhaust gas so much that they can be vented with CPVC or Polypropylene (plastic) pipe, instead of the steel venting required by conventional boilers. They produce cooler exhaust because the extra heat has been harvested and transferred to the water in your heating system.

Basic steam generation system on a diesel ship - Bright

The exhaust gas boiler is basically a heat exchanger with a row of tube banks, through which the feed water passes. Over these tubes hot exhaust gases are allowed to pass. Thus, just in the case of a normal heat exchanger, the heat is transferred from the hot gases to the feed water converting the later into steam.

All manufacturers of cast iron boilers want the Delta Δ T of the boiler with a certain range. Some are 20°F while others are 30°F.

Plant Engineering | Selecting the right boiler

A condensing boiler offers very high efficiency by recovering the latent heat of vaporization from the boiler exhaust. In natural gas-fired boilers this is accomplished with a feedwater return at temperatures below 135° F. If your feedwater return is usually above this temperature, there is no efficiency benefit with the condensing design, and

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived

Air Fuel Ratio Effect on Combustion Efficiency

Combustion efficiency is dependent upon using the right amount of air to consume the fuel. In fuel-fired process heating, the largest source of energy loss is through the exhaust stack, which is why managing air flow is essential to combustion efficiency. When fuel burns in the presence of oxygen it is converted to carbon dioxide, water and heat.
