Gas & Oil Boiler Series
D-type water-tube and packaged fire-tube boilers for industrial plants, commercial buildings and district heating. Designed for clean combustion, high efficiency and reliable long-term operation.
Gas & Oil Boiler Solutions for Industry
Designed around the real questions from plant owners, EPC contractors and facility managers when selecting a gas or oil fired boiler.
What type of gas & oil boilers do you supply?
ORL supplies packaged gas & oil fired boilers in D-type water-tube and fire-tube configurations. The boiler body is installed on a steel underframe as a complete module, with furnace, convection bank, drums and piping integrated for fast installation and easy connection on site.
Which fuels can the boiler use?
Standard designs fire natural gas, city gas, LPG and light fuel oil. Dual-fuel burners allow automatic changeover between gas and oil according to fuel availability. Heavy oil or special fuels can be evaluated case by case by our engineering team.
What are the typical applications?
Gas & oil boiler series are widely used in factories, food & chemical plants, hospitals, schools, hotels, office buildings and district heating networks. The compact structure and clean combustion are suitable for areas with strict environmental and space requirements.
How is high efficiency achieved?
The furnace adopts membrane water-cooled walls and optimized gas flow, ensuring full heat transfer in the radiant and convection sections. Optional economizers and air preheaters can be added to recover exhaust heat and reduce fuel consumption.
How do you control NOx and other emissions?
Low-NOx burners, staged combustion and flue gas recirculation can be configured to meet local emission limits. We can also reserve interfaces for external flue gas treatment systems such as SCR and desulfurization equipment when required by the project.
What about installation and operation?
The boiler, burner, valves and control cabinet are pre-assembled and tested in our workshop. On site, the unit only needs to be positioned, connected to utilities and commissioned. Fully automatic control, safety interlocks and monitoring functions simplify day-to-day operation.
