Condensing Boiler Flue Gas Temperature

Flue Gas Condensing Temperature - HVAC-Talk: 2008-3-13 · As I am now dealing with a job that has Lochinvar CHHN0990 non-condensing boilers that were condensing in the boiler as well as the flue, I've done a little search and found that natural gas flue gas condenses at 60C, which equals 140F. Coincidentally, that is the minimum allowable return water temperature to these boilers.

A thermodynamic approach on vapor-condensation of

2008-6-1 · To estimate quantity in moles of vapor-condensed deposits from flue gas at 350–550 °C, which correspond to the tube wall temperatures of most practical boilers, equilibrium flue gas composition was firstly obtained at 650–950 °C, and the gas species in these gases were quenched to cold tube walls by conducting another series of equilibrium calculation at 350–550 °C.

BIOMASS BOILER WITH FLUE GAS CONDENSATION |

Condensation increases the efficiency of moist biomass boilers. The control of excess air is based on the measurement of the oxygen concentration (by zirconium dioxide detector) at the flue gases. Depending on this value the boiler programmer adjusts the feed rate of wood fed into the furnace in order to maintain a constant oxygen concentration.

PROTECTING BOILERS AGAINST FLUE GAS

These biomass fuel boilers require protection against sustained flue gas condensation and can be equipped with the same type of hardware to provide that protection. However, the flue gases of such biomass boilers contain vastly more chemical pollutants and particulates than propane and natural gas boilers.

Condensing boiler | Jeremias UK - chimney 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 gases are cooled well below 120°C hence the maximum condensate happens in the flue system chimney. The condensate then flows along the internal wall of the pressure-tight pipe, back to

Commercial boiler flue systems - Hamworthy Heating

Flue gases may be discharged through either a concentric or twin duct flue system. The plant room requires ventilation in accordance with BS5440 and BS6644. Plant rooms will require less ventilation than open flue systems, and with reduced air flow, warmer room temperatures are possible – a useful point when designing tighter buildings.
