Product Overview
The Steam Power Plant ThermoFlux – 7090 integrates all major components of a complete steam power cycle into a single bench-scale unit. The vertical fire tube boiler is constructed from SS 304, operates up to 7 bar, and is fired by an automatic on/off LPG/LNG or oil-fired forced draft burner with atomizer. Two high-pressure switches, one mechanical high-pressure safety device, and temperature safety controls by digital temperature controller and bimetallic switch are included. A mis-fire safety system is built into the burner.
The feed water system includes a mini RO unit, a soft water tank, a feed water pump, and digital temperature sensor display. Both automatic and manual operation modes are user-selectable. The fuel system includes a fuel tank and a fuel flow meter. The complete boiler assembly is packaged on a skid for easy installation.
The single-stage impulse axial turbine with Curtis wheel delivers a maximum continuous output of over 25 W and operates at speeds of approximately 18,000 to 30,000 rpm with atmospheric exhaust pressure. Turbine runner diameter is 55 to 75 mm. A water-cooled shell and tube condenser handles condensate recovery.
The DC generator is rated at 50 VA, self-excited or permanent magnet type, with an output of 24 to 220 VDC at 3000 rpm. Four 15 W load lamps are included. A voltmeter, ammeter, generator speed sensor, and indicator are fitted in the generation section. Speed sensors, steam inlet and outlet temperature sensors, and a steam inlet pressure gauge are included in the turbine instrumentation section.
An optional water tube superheater (gas fired) is available, along with a cooling tower, separating and throttling calorimeter, and steam lagging accessories.
