“Create a steam circuit turbo alternator diagram for a biomass condensing plant: wood-chip fuel to a biomass boiler and 65 bar 480 C superheater, a condensing steam turbine driving an alternator, a generator step-up transformer to a 33 kV export feeder, and a condenser-hotwell-condensate pump-deaerator-feed pump-economizer return path to the boiler drum.”
Lee las decisiones que hay detrás.
Exhaust heat is rejected in a surface condenser to maximize electrical expansion.
The boiler and superheater supply 65 bar, 480 C steam.
The generator output is stepped up for a 33 kV export feeder.
Condensate moves through a hotwell, deaerator, and feed pump before boiler return.
Use this template for a standalone biomass generator with a condensing turbine and grid export. It contrasts with a backpressure cogeneration circuit that supplies process steam.
Preguntas habituales
Why is the turbine called condensing?
Its exhaust enters a condenser, allowing expansion to low pressure for more electrical generation.
What is the hotwell?
It is the condenser collection point for recovered condensate before pumping.
Why step up generator voltage?
A higher feeder voltage reduces current and losses for power export.
