Feed Water Supply TRIZ Cases
- Exhaust steam waste heat recovering and supplying system of air-cooling units in large thermal power plants
See how independent exhaust extraction systems with dual ejectors and pre-condensers maximize w
- Steam Silencer Porous Outlet Structure for Water Hammer Reduction
Submerged porous outlet ports disperse steam into drain to speed condensation and reduce water hammer, noise, and pipe damage.
- Submerged Steam Silencer With Porous Outlet to Reduce Water Hammer
Flash steam is dispersed through submerged porous outlets so it condenses faster in drain, reducing water hammer, noise, and pipe damage.
- Concrete Pipe Pile Steam Pressure Boosting and Heat Recovery
Pressure boosters and a blowdown flash tank raise low-pressure steam for concrete pipe pile curing while recycling residual heat for heating.
- Evaporator Liquid Drain Piping for Vertical Vessel Level Control
Liquid drain piping returns fluid to the heat transfer section, lowering the vertical vessel level to reduce friction pressure loss and prevent water carryover.
- Convaporator System for Exhaust-Free Steam Generation
A convaporator system generates saturated steam using a close-coupled heat exchanger and separation tank.
- Economizer Syphon for Iron Removal in Once-Through Steam Generators
Bent tubes create a syphon that drains iron-rich water from the economizer to a hotwell, eliminating mechanical separators and reducing steam generator weight.
- Steam-Driven Pump System for Cavitation-Free Water Supply
A steam-driven pump system uses high-pressure steam to automatically suck and supply water from a source.
- Vertical Heat Recovery Steam Generator Low-Pressure Flow Stability
Segmented low-pressure preheaters generate sufficient pressure drop for stable flow while preventing tube corrosion through preliminary temperature control.
- Flue Gas Cooler Steam Prevention via Bypass Circulation
Bypass pump circulates feed-water through a flue gas cooler to maintain cooling during shutdown.
- Dual Turbine Rotor for Waste Heat Energy Recovery
Two turbine wheels on a shared rotor expand working fluid sequentially, recovering waste heat that would otherwise dissipate into the environment.
- Industrial Heat Pumps Preheat Boiler Feedwater
Cascaded industrial heat pumps elevate feedwater temperature using waste heat from flue gas and condenser water, reducing fuel consumption by over 7%.
- Closed Drain Recovery System with Condensing Unit
A closed drain recovery system uses a condensing unit in the makeup water tank to condense flush steam.
- Drain Recovery System Pressure Equalization
A drain recovery system with a buffer tank and assist tank equalizes pressure between inner spaces to supply feedwater.
- Expansion Machine Lubrication via Multi-Stage Pump Branching
Multi-stage pressure-increasing apparatus taps intermediate pressure to supply bearing lubricant, eliminating throttling energy losses and component complexity.
- Drain Recovery Device Boiler Pressure Stabilization
Dynamic control of the recovery tank water level reduces low-temperature make-up water mixing, preventing boiler pressure drops during high loads.
- Heat Recovery Ejector with Temperature Control
An ejector mixes steam drain with circulating water to recover heat in a closed tank loop.
