EQUIPMENT FOR THE STEAM CYCLE At this page the main equipment for the steam cycle is shown
Feed water tank / deaerator: The feed water tank contains a one hour feed water reserve at boiling temperature. The tank is heated up by turbine bleeding steam. Further more the dissolved oxygen and CO2in the feed water will be removed.
Boiler feed water pump
This pump is a high pressure pump that transfers the condense from feed water tank into the steam boiler. The discharge pressure of these pumps is higher than live steam operation pressure.
Condense pump
The condense pumps are low pressure pumps that transfers the condensate from steam condenser or low pressure heater to the feed water tank.
cooling water pump
The cooling water pumps are designed for high volume flows to supply the cooling water from cooling towers or natural sources to the steam condenser.
Valves and piping: The valves in the plant can be operate with electric and pneumatic drives or manual.
Demin water plant: During plant operation boiler water from steam cycle is lost. This loss has to be balanced by demineralized water that is produced by the demin plant. The demin water plant refurbishes the water from natural sources into water with boiler water quality (removal of all dissolved materials). The plant consists of different filters, RO membranes, mixed bed polisher and chemical dosing units.

Steam boiler
The flue gas heat coming from ETAComb furnace passes the boiler and generates the steam. The used boiler type is a water-tube boiler. The hot flue gas passes the boiler trough radiant chamber, two stage superheated, evaporator, economiser and air preheated. The flue gas is cooled down in the boiler up to 160°C. The transferred heat heats up the boiler feed water and generates the superheated steam with temperature up to 450°C.

Fuel gas Dedusting
Fuel gas deducting
The flue gas cleaning plant controls the environmental dust pollution and the life time of the recirculation gas duct system and recirculation gas fan.
For cleaning of the recirculation gas multi cyclones are used that can remove the fly ash to sufficient clean gas values.
The bag filter is used for cleaning the flue gas that passes the stack. With a bag filter the dust content could be reduced up to <10 mg/m³.
The result is that the ETAPlant emissions couldn‘t be observed at the stack. Flue gas bag filter

Cooling Systems And Condensing
Wet cooling tower – fan driven
Condensing and cooling system
The condensing and cooling system consists of the steam condenser that returns the steam fully into liquid form. The condensing process emits heat that is transferred to the cooling water. The cooling water for the condenser is supplied from the cooling tower. After condenser the water is heated up to 40°C. This warmed up water returns back to the cooling tower and it will be sprayed in this one. The water is cooled down by water evaporation and ambient air at atmospheric conditions and is collected at cooling water basin. From here it feeds the steam condenser by cooling water pump.

Turbine Generator
Complete mounted turbine with gear box
Steam extraction turbine – cross section
Turbine generator plant – schematic drawing
Turbo generator plant The turbo generator plant consists of the steam turbine and the generator.
The generator is driven by a steam condensing turbine. The steam expands in the turbine and turns the turbine shaft. The turbine shaft is connected with the generator shaft by gear. The expansion of the steam is generally performed in multi stages. After some stages an amount of steam is bleeder of the turbine and is used for heat recovery. The pressure at the turbine exhaust side is bellow the atmospheric pressure. This allows a high electric efficiency.
To avoid a overheating of the generator it is air / water cooled.

Eefficiency Increasing
Under the point of view of worldwide raising fuel costs and shortage in fuel supply an advanced power plant should be well engineered to achieve a good plant efficiency.
The main target is to reduce the heat losses at the plant and to increase the electric energy production. The main heat losses are: - the cooling tower air/evaporation loss (heat transfer from steam condenser) can be reduced by bleeding steam heated condensate repeaters and the flue gas heat loss at stack can be reduced by patented ETAComb recirculation gas technology.
