Condensing boilers | Jeremias® Exhaust Systems

The high efficiency of the condensing boilers results from the fact that heat produced in the condensation process is used to increase heat supply. The exhaust gasses are cooler and hence the maximum condensing happens in the chimney. The condensate then flows along the internal wall of the pressure-tight pipe, and back to the boiler for disposal.

Increasing Natural Gas Boiler Efficiency by Capturing

fabricated, and installed to recover the waste flue gas energy from a natural gas fired boiler. The recovered energy is used to preheat boiler makeup water and combustion air. Preheating makeup water, using the energy in the stack flue gas, increases boiler efficiency 6 percent to 8 percent annually.

How to Maintain Hot Water Heating Systems - dummies

Hot water heating systems need a little maintenance, like venting the radiators and draining the boiler, to keep things running efficiently. Gravity and hot water furnaces are not often installed in new homes today, but similar systems with the old cast-iron radiators throughout the house were fixtures in homes built around 1900, and some of []

Simple Guide for Choosing the Most Efficient Boiler

Oct 31, 2017· As a result, the temperature of the exhaust gas falls below the dew point, which causes water vapor in the exhaust to condense into a liquid. Condensing boilers can usually achieve an annual fuel-utilization efficiency (AFUE) of 90% or higher and are usually gas fired.

Waste Heat Reduction and Recovery for Improving Furnace

Use of a waste heat boiler to recover part of the exhaust gas heat is an option for plants that need a source of steam or hot water. The waste heat boiler is similar to con- ventional boilers with one exception: it is heated by the exhaust gas stream from a process furnace instead of its own burner.

Waste Exhaust Heat Boilers - Clarke Energy

Apr 26, 2019· Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450oC as high grade heat, contrasting to low-grade heat available from the generator cooling circuits.
