US6609483B1 - System for controlling flue gas exit

A system for maintaining an optimal flue gas inlet to a boiler mounted SCR assembly in the flue of the boiler is accomplished by mixing the normal inlet feedwater to an economizer of the boiler with near saturation water from downcomers of the boiler to thereby raise the temperature of the flue gas passing across the economizer and raising the SCR inlet to the desired optimal SCR operation

Flue_gas_stack : definition of Flue_gas_stack and

A flue-gas stack is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or other large combustion device.

2016-8-17 · The boiler may under no circumstance carry the weight of the flue gas funnel or the exhaust gas funnel. Fix-points should be arranged for the funnels right below and above the boiler. The exhaust gas inlet piping should be designed so that the exhaust gas flow is evenly distributed over the entire inlet cross-section area.

Why Boiler Keeps Losing Pressure - UK Leak Detection

In a combi boiler, it is a water/water exchange as the gas heated water passes across a coil while the cold water heading to a hot tap is exposed to the maximum surface area. When these fail the radiator heating system water comes out the hot tap, often a bit discoloured with an immediate drop in pressure and a horrible taste.
