Design Guidelines for Humidification Systems

An isothermal humidification system includes a pressurized steam boiler or an evaporative steam generator, control components, and a dispersion assembly. While an evaporative steam generator or atomizing pumping station can be placed in numerous locations, proper placement of the dispersion assembly and control components is crucial.

Myths and methods for protecting boilers against flue-gas

Aug 14, 2017 · That statement is absolutely true. If the combustion-side surfaces of any boiler's heat exchanger drop to or below the dew-point temperature of the exhaust gases, condensate will form in any boiler burning a hydrocarbon fuel such as natural gas, propane, fuel oil, firewood or pellets.

Boiler Walls Acid Dew Point Corrosion

May 24, 2017 · Boilers, the profit center is a common location to find problematic issues with acid dew point corrosion. Cold steel allows interior condensing of flue gases (on the cooled steel surface acid enriched gases condense from gas state to liquid state) reeking havoc in operations because of steel lose and holes hidden under cladding and insulation.. These cold spots also weaken the refractory and …

FLUE GAS HEAT RECOVERY – ECONOMIZER – DEW POINT …

FLUE GAS HEAT RECOVERY – ECONOMIZER – DEW POINT CORROSION? In the industry, significant amounts of energy are lost via the stack. Stack losses are concentrated and therefore a great place to recover heat. However, acid dew point corrosion has been stopping operators from recovering this heat. But not any longer!

Fuel Ash Corrosion - National Board

Dew-point corrosion is exacerbated in coal-fired boilers by the presence of fly ash. Fly ash accumulates throughout the flue-gas path, and the resultant deposit acts like a sponge to collect both moisture and acid, especially during shutdown cycles. One other corrosion problem associated with oil ash is the potential for acid corrosion

Superheated steam - Wikipedia

Superheated steam is steam at a temperature higher than its vaporization point at the absolute pressure where the temperature is measured.. Superheated steam can therefore cool (lose internal energy) by some amount, resulting in a lowering of its temperature without changing state (i.e., condensing) from a gas, to a mixture of saturated vapor and liquid.If unsaturated steam (a mixture which

DewPoint 6210 Hay Steamer | Hay Steamer DewPoint 6210

The byproducts created when burning natural gas to fire your boiler have a dew point of around 130ºF. This means that in order to get that condensation to appear on the heat exchanger, the water cycling through your radiators must be 130ºF or lower.

Low Temperature Corrosion in Boiler and Its Prevention

For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 250°F to prevent condensation and possible stack or stack liner corrosion. The condensing economizer improves waste heat recovery by cooling the flue gas below its dew point, which is about 135°F for products of combustion of natural gas.

Boiler Corrosion Prevention for Waste & Biomass Boilers

Dew-Point Corrosion in WtE and Biomass Boilers. When the temperature of the flue gas decreases, gasses present in the environment reach saturation and droplets of liquid start to condense on solid surfaces. The saturation temperature depends on the load of the concerned gaseous species and (for sulfuric acid) on the humidity of the flue gas.
