“SIEVENT” FGD SCRUBBER for 100 % PET COKE — FIRED BOILER.. PROPOSED SCHEME; The flue gases are passed through the proposed Scrubber (combination of Venturi and Sieve Tray) at the downstream of ESP and ID Fan .. The proposed Scrubber is designed to De-Sulphurize the Flue Gases in three stages, namely :. PRIMARY TREATMENT.

The flue gas exits the cyclones to a plenum chamber in the top of the regenerator. The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam.

: 379KBFlue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat. Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel.

2013-11-27 · The excess air is measured by excess oxygen in the Flue Gas at Air Preheater inlet and outlet. It is always advisable to maintain the optimum level of excess oxygen in the furnace. Higher excess air than optimum - more Dry Flue Gas loss, Boiler cooling, reduced steam generation, more penalty on auxiliary power consumption, higher

Flue Gas boilers are the significant energy saving equipment, utilize the heat in flue gas from combustion processes or hot extract air from industrial processes to generate hot water or saturated steam Otherwise, the flue gas boiler could be used in oil gas fired combined cycle units, and take advantage of the high temperature flue gas heat discharged by gas turbine

2  · Alfa Laval Aalborg offers a series of highly efficient waste heat recovery boilers that extract heat from hot flue gases and generate steam or hot water. A boiler is easily added to your flue gas stream and recovers heat that would normally be released into the air through a chimney. There are many possibilities to profit from recovered heat.

Flue gases on steam boiler plant are not condensed, therefore the actual amount of heat available to the boiler plant is reduced. Sophisticated electronic control systems that monitor all the components of the flue gas, and make adjustments to fuel and air flows to maintain conditions within specified parameters. a boiler plant should

2020-1-28 · A heat exchanger utilisation the waste heat in flue gas of the steam boiler or steam generator itself for increasing the boiler efficiency, is called an ECONOMISER. It can be used for preheating the feed water, but also for external purposes including preheating of make-up water, domestic water or central heating water.
