A Warning About Cracked Heat Exchangers in Gas Furnace

The heat of the combustion gas raises the temperature of the metal, and as the air from the blower passes around it, heat transfers to it. Basically, the heat exchanger is where the furnace heats the air! Why Is a Cracked Heat Exchanger a Problem? Because it allows the exhaust fumes inside the exchanger to leak into the air.

AMENDMENT TO STANDARD TECHNICAL

Clause No. 1.1 (iv) Gas to gas heat exchanger (GGH):The use of gas to gas heat exchanger (GGH) in FGD system has got both merits and demerits. The GGH has advantage of reducing the temperature of inlet raw flue gas to the absorber which reduces potential of damage to scrubber internals in case of flue gas excursion and mal- operation etc. Application of Jiema MGGH System in De-whitening of Application of Jiema MGGH System in De-whitening of Industrial Exhaust Gas. De-whitening means that when the saturated wet flue gas discharged from the chimney is in contact with the ambient air with low environment, during the cooling process of the flue gas, the water vapor in the flue gas is supersaturated and condensed, and the condensed water droplets refract and scatter the light, thereby the plume is

Constructal allocation of heat transfer area in Flue Gas

FGD (Flue Gas Desulfurization) system is introduced in this paper for maximizing the heat exchangers included in it. The heat exchangers are composed of the cooler and reheater, which are called non-leakage GGH. The term Non-leakage is added to GGH (Gas-to-Gas Heater) because the flue gas is not leaked into the atmosphere with FGD process.

Corrosion in the Flue Gas Cleaning System of a Biomass

After that it is led through the gas/gas heat exchanger (GGH) which is a rotating regenerative heat exchanger on a counter flow principle. The GGH has inlet flue gas (approx. 50°C) from the FGD and the flue gas is heated to approx. 300°C so that removal of NOx gases can occur in the denitrification unit (DeNOx). This clean gas returns to the GGH where the outlet temperature is 80-90°C. Corrosive flue gas is no longer a show-stopper for heat Typically, flue gas is sent out the stack at elevated temperatures of 150 C and up. As a result, around 10% of the process heat is lost to atmosphere. Corrosion concerns have up to now stopped operators from recovering this heat. This corrosion arises from sulphuric acid condensation from the flue gas at temperatures below the acid dew point (ADP).

Many flue gas cleaning processes contain some form of heat exchange between the untreated flue gas and the treated flue gas. In the wet limestone FGD processes, the untreated flue gas is cooled before it enters the absorber, and the treated gas is heated before entering the stack. In the Tail-end SCR process, the heat flow is the reverse, with Heat Exchangers:Effectiveness-NTU AnalysisA shell-and-tube heat exchanger must be designed to heat 2.5 kg/s of water from 15 to 85°C. The heating is to be accomplished by passing hot engine oil, which is at 160°C, through the shell side of the exchanger. The oil provides an average convection coefficient ho = 400 W/m2·K on the outside of the tubes. Ten tubes pass water through the
