Products Description
Steam is essential in feed production. It conditions raw materials before pelleting, stabilizes pellet durability, and supports cleaning and sterilization. A feed factory steam boiler must deliver consistent pressure, run reliably through long shifts, and keep fuel cost predictable. This boiler is built to meet those requirements.
Suitable for feed mills, animal feed plants, and aquafeed production lines, it covers capacities from 1 to 20 tons per hour and supports multiple fuel types.
Why Feed Mills Need Stable Steam
Feed pelleting lines depend on steady steam pressure. When pressure fluctuates, conditioning temperature changes, and pellet quality and output rate drop. This boiler maintains stable steam pressure during peak production, so the pelleting line runs at a consistent setting.
Beyond pelleting, the boiler supplies steam for:
- Raw material heating and conditioning
- Equipment and workshop cleaning
- Sterilization of production areas
- Other steam-consuming processes on site
Capacity is matched to the production line size, avoiding both undersupply and wasted fuel from oversizing.
Design and Construction
The boiler structure is selected by capacity: smaller units use a fire-tube (WNS) design for compact layout and easy maintenance; larger units use a water-tube (SZL) design for higher steam output and faster load response.
Heating surfaces are arranged to maximize heat transfer. The furnace uses high-temperature-resistant materials and is built to pressure-vessel standards. All welds undergo radiographic testing, and every unit passes hydrostatic pressure testing before shipment.
Production equipment
Fuel Options
Fuel availability varies by region. The boiler can be configured for:
- Natural gas, LPG, diesel, heavy oil
- Coal (bituminous, anthracite)
- Biomass pellets, wood chips, agricultural residues
If the factory generates waste such as wood scraps or crop residues, a biomass configuration can reduce fuel cost significantly. The fuel type is confirmed at quotation stage so the boiler and burner are matched correctly.

Efficiency and Operating Cost
01
Fuel is the largest ongoing expense for any boiler. This unit uses high-density rock wool insulation to reduce heat loss, and the control system modulates burner output based on actual steam demand rather than running at full power continuously.
02
An optional economizer recovers heat from exhaust gas to preheat feedwater, further reducing fuel consumption. For a 4 t/h gas boiler running 16 hours per day, an economizer typically cuts fuel use by 3–5%.
Control and Safety
The automatic control panel lets operators set pressure thresholds, and the system adjusts firing rate accordingly. Feedwater level is monitored continuously with automatic makeup.
Standard safety features include:
- Low-water cutoff
- Overpressure protection with safety valve
- Flame failure detection and fuel shutoff
- Exhaust temperature alarm
- Pressure gauge and thermometer dual display
These interlocks protect the equipment and prevent unplanned shutdowns, since a boiler offline means the entire feed line is offline.

FAQ
Q: Can the boiler run on both gas and diesel?
A: Yes, dual-fuel burners are available. The burner switches between fuels automatically based on availability and cost.
Q: Do you provide installation?
A: We provide installation drawings and on-site supervision. Full installation by our team is available at additional cost.
Q: What is the boiler's service life?
A: With proper water treatment and annual maintenance, the boiler pressure body has a design life of 20 years or more.
