> Fuel Oil Gas Fired Boiler
WNS Series Oil & Gas Fired Boiler is a horizontal three-pass fire tube boiler designed for high efficiency and stable performance.
1. High Thermal Efficiency --- Adopts horizontal three-pass fire tube structure with large heating surface and optimized combustion chamber, achieving thermal efficiency up to 98–99%.
2. Low Emissions --- Equipped with advanced low-NOx burners to ensure clean combustion and compliance with environmental standards.
3. Fully Automatic Operation --- Integrated PLC control system enables automatic ignition, load adjustment, safety interlock, and fault alarm for convenient and reliable operation.
4. Energy-Saving Design --- Large diameter corrugated furnace and threaded smoke tubes enhance heat transfer, reducing fuel consumption and operating costs.
5. Safe & Reliable --- Multiple safety protections including over-pressure, over-temperature, flame failure detection, and water level protection ensure stable long-term operation.
6. Compact & Easy Installation --- Skid-mounted or packaged structure allows quick installation and simple maintenance.
> Vertical Diesel Lpg Gas Boiler
Model: steam generator, steam boiler, hot water boiler
Structure: water tube once through design, fire tube two pass design
Vertical boiler occupies minimal floor space and reduces installation area. Compact and efficient, it provides reliable steam or hot water supply with easy installation and fast start-up.
> Electrical Boiler
Electric boiler uses electricity as the heat source to produce Hot Water/Steam by electric heating elements. Electrical energy is converted directly into heat and transferred to water inside the boiler.
No combustion, no flue gas, and no fuel storage, realizing clean operation and stable steam output, precise control and reliable safety protection.
Model: LDR series, WDR series
Structure: vertical, horizontal
Standard: normal, food-grade stainless steel
> Coal Biomass Fired Boiler
Feeding system: manual, automatic
Structure: fire tube, water tube
Type: vertical, horizontal
Combustion: wood biomass coal
LHS LSS Series Solid Fuel Boiler
Vertical coal biomass fired steam/hot water boiler, widely use in industrial heating system, small factory production heating drying, commercial laundry.
DZL DZW Series Automatic Coal Biomass Boiler
Automatic coal/biomass feeding system, high combustion efficiency for wood biomass. Optional chain gate, travelling grate, reciprocating grate stoker.
SZL Series Water Tube Boiler
Coal biomass fired water tube boiler with double drums. water membrane wall design boiler. larger combustion furnace. Combustion use chain grate or reciprocating grate stoker.
