The Danger of Sulfur in a Gas Turbine - Identifying Threats

Jul 28, 2020 · The hot exhaust gases pass through several steam drums in the HRSG and release heat to produce superheated steam. If the flue gas at the latter stages, notably the evaporator, the economizer and the stack, are below its acid dew point, the gaseous acid will start to condensate and cause serious corrosion problems for the equipment.

Boiler Furnace Pressure Excursion and Set Points

The flue gas being pulled out f the furnace by the ID fan is now being replaced only by preheated air rather than by the products of combustion in the firing zone. The average temperature of the gases resident in the furnace (or other subsystem) at any given time following fuel trip will decrease rapidly. Because of the temperature drop, the

tertiary air injection ports are used to ensure complete combustion of the gas phase components volatilised from the solid waste. Typical regulations require the flue gas to be held at a minimum temperature of 850 o C for two seconds after the last injection of combustion air. The hot flue gas then passes into the water tube waste heat recovery

Negative Impacts of Incineration-based Waste-to-Energy

Landfilling generates methane. Methane = >20 times worse green house gas than CO2. Instead of landfilling the garbage, burning it reduces green house gas emissions, boosts recycling (because those metals are worth a pretty penny), and eliminates the NIMBY syndrome of future landfill sites.

US4911900A - Method of removing nitrogen oxides from a

In the selective reduction of nitrogen oxides of flue gases with ammonia, the ammonia is added as ammonia water upstream of the reduction zone. Residual gas phase ammonia and ammonia compounds collected with the flyash serve as recycled ammonia sources and ammonia is formed from them and, in an ammoniacal solution, is added to the ammonia water supply vessel.

Dec 03, 2009 · A stack temperature gauge is normally installed on a boiler to indicate the temperature of the flue gas leaving the boiler. The lower the flue gas temperature, the more efficient the system. Approximately 1% of boiler thermal efficiency is lost for a 40°F increase in stack temperature.

Waste-to-energy plant - Wikipedia

A waste-to-energy plant is a waste management facility that combusts wastes to produce electricity.This type of power plant is sometimes called a trash-to-energy, municipal waste incineration, energy recovery, or resource recovery plant.. Modern waste-to-energy plants are very different from the trash incinerators that were commonly used until a few decades ago.
