NEO MAKİNA ve MÜHENDİSLİK A.Ş. offers industrial steam turbines and cogeneration solutions that let plants generate electricity from steam they already produce. Back-pressure and condensing turbines from 100 kW to 5 MW replace the pressure-reducing valve in food, textile, paper, sugar, chemical and biomass plants and convert lost energy into power.
How Does an Industrial Steam Turbine Work?
High-pressure steam from the boiler expands across the turbine blades and turns the rotor, which drives the generator through a gearbox. In a back-pressure turbine the exhaust steam is delivered to the process at its required pressure (e.g. 3–10 bar); in a condensing turbine the steam expands down to vacuum for maximum electricity.
Turbine Types
Back-Pressure Turbines
- Application: Converts the difference between boiler pressure (e.g. 20–40 bar) and process pressure (3–10 bar) into electricity; installed in place of the pressure-reducing valve (PRV).
- Efficiency: Because exhaust steam is used in the process, total energy efficiency is 85–90%.
- Investment: No condenser or cooling tower; the lowest-cost option.
Condensing and Extraction Turbines
- Application: Plants with surplus steam or electricity priority; biomass and waste-to-energy plants.
- Flexibility: Extraction provides both process steam and maximum electricity.
Single-Stage Small Turbines
- Application: 100–1,000 kW pump, fan and compressor drives or small generator sets; simple construction, low maintenance.
Cogeneration and Waste Heat Recovery
- Cogeneration (CHP): An existing solid-fuel or biomass boiler is raised to higher pressure to produce electricity first, then process steam.
- Waste heat: Steam raised in waste-heat boilers on furnaces, dryers and engine exhausts is used in the turbine.
- Energy cost: Generated electricity displaces grid power; typical payback 2–4 years.
Typical Application Range
- Output: 100 kW – 5 MW (for larger units see Industrial and Utility Steam Turbines)
- Inlet steam: 10 – 65 bar, saturated or superheated up to 480 °C
- Exhaust: 0.1 – 12 bar back-pressure or condensing
- Speed: 3,000 – 12,000 rpm (geared)
- Standards: API 611, IEC 60045-1, CE
Scope of Supply
- Feasibility: steam balance, generatable power and payback calculation.
- Turbine-gearbox-generator set, lubrication unit, control and protection (speed governor, overspeed protection).
- Steam and condensate piping, electrical connection and grid synchronisation.
- Installation, commissioning, operator training and periodic maintenance.
Frequently Asked Questions
How much steam do I need to install a turbine?
As a rule of thumb, every 10 t/h of steam reduced from 20 bar to 5 bar produces about 500–700 kW in a back-pressure turbine. The exact figure is calculated from steam temperature and flow profile.
Will it work with my existing boiler?
Yes, if boiler pressure is well above process requirement (at least 8–10 bar difference). For low-pressure boilers a boiler-upgrade feasibility is prepared.
Can I sell to the grid?
Yes. Grid connection and synchronisation are designed under unlicensed-generation regulations; priority is the plant's own consumption.
