NEO MAKİNA ve MÜHENDİSLİK A.Ş. designs, manufactures and commissions water-tube hybrid steam boilers for industrial plants. Available in vertical and horizontal configurations, our boilers meet high-pressure, superheated-steam and low-emission requirements in a single unit.
What Is a Water-Tube Hybrid Steam Boiler?
A hybrid boiler combines the strengths of water-tube and fire-tube designs: the furnace and radiant zone are built from water-tube membrane walls, while the convection zone uses a fire-tube bundle. The result is fast steam generation, high pressure capability and a compact footprint. Solid, liquid and gas-fired versions are available.
Configuration Options
Vertical Water-Tube Hybrid Boilers
- Compact layout: Vertical tube bundle provides a large heat-transfer surface in limited space.
- Fast steam response: Low water volume allows quick reaction to sudden load changes.
- Easy maintenance: Accessible tube bundle and inspection doors keep downtime short.
Horizontal Water-Tube Hybrid Boilers
- Large capacity: Continuous steam supply for food, textile, petrochemical and power plants.
- Low pressure drop: Optimised water-steam circulation for high energy efficiency.
- Expandable design: Modular structure allows future capacity increases.
System Components and Operating Principle
- Water tubes and membrane wall: Carbon or alloy steel tubes selected for the operating pressure; diameter and wall thickness calculated to ASME Section I / EN 12952.
- Furnace: Refractory-protected combustion chamber designed for the fuel type, with staged air for low NOx.
- Convection bundle and superheater: Saturated or superheated steam (up to 450 °C) via a separate superheater package.
- Heat recovery: Economiser and air preheater lower flue-gas temperature and reduce fuel consumption.
- Automation: PLC-based control of water level, pressure, flame supervision, fuel dosing and remote monitoring from one panel.
Typical Application Range
- Steam capacity: 2 – 50 t/h (higher on a project basis)
- Operating pressure: 10 – 40 bar
- Steam temperature: saturated or superheated up to 450 °C
- Fuel: coal, biomass, pellets, fuel oil, natural gas or multi-fuel versions
- Boiler efficiency: above 90% with economiser (depending on fuel and operating conditions)
Efficiency and Environmental Measures
- Low-emission combustion: Staged air and controlled furnace temperature for low NOx.
- Insulation: Mineral wool or ceramic fibre insulation keeps surface heat loss to a minimum.
- Condensate recovery: Integrated condensate tank and deaerator save water and energy.
The NEO MAKİNA Difference
Every boiler is engineered for the plant's pressure, temperature and flow requirements. At the proposal stage we provide efficiency and operating-cost calculations based on fuel analysis and load profile. Installation, commissioning, operator training and spare-parts support are covered by NEO MAKİNA. Our references include a 12 t/h, 38 bar, 450 °C superheated-steam water-tube boiler project.
Frequently Asked Questions
How does a hybrid boiler differ from a conventional fire-tube boiler?
Fire-tube boilers are generally limited to around 20 bar and medium capacities. The hybrid design, with its water-tube furnace, allows higher pressures and superheated steam.
Which fuels can it burn?
Separate furnace designs are available for solid fuels (coal, biomass, pellets), liquid fuels and natural gas; multi-fuel versions are offered on a project basis.
What are the delivery time and scope?
Manufacturing takes 3 – 6 months depending on capacity. Scope is planned turnkey: boiler, firing system, feed-water unit, stack and automation.
