Dunphy Combustion Ltd. products

The `T` series of monobloc, axial air flow burners are designed for use with all liquid and gaseous fuels and are suitable for industrial, process, property, waste to energy, drying and wastewater treatment applications. The burners` axial air flow produces the uniform air distribution essential to ensuring high combustion efficiency across a wide turndown range at ALL levels of firing. Typically, our `T` series burners achieve turndowns of: 10:1 on gas, 4:1 on oil and 8:1 on steam/air atomisation

Dunphy Duobloc burners are supplied for a wide range of applications and designed to match specific customer needs and / or site requirements. Units supplied are therefore variants of a basic, standard design.

Dunphy gas boosters provide a maximum pressure lift of 120mbars and a maximum volume of 3000m³/hr.

Dunphy bespoke or standard burners are key components of high efficiency, low emission waste to energy bio gas systems. Our burners are ideal for standard incineration, bio gas and bio fuel heat and steam generation. We have international experience in designing and customising axial air flow, box and utility burners to match specific site conditions and the individual characteristics of waste derived fuels.

Dunphy has developed a range of solutions for safe and efficient co-firing of fossil fuels, liquid bio fuels and gaseous fuels derived from recovered waste sources.

The world’s focus on safety and environmental protection is steadily transforming old industrial processes into cleaner, more efficient practices.  Dunphy process burners offer a clean combustion solution by reducing pollution & running costs, whilst maximizing heating performance and increasing overall production. Dunphy design a broad range of low NOx, ultra low-NOx and next-generation process burner systems that meet the ever growing European NOx expectations and achieve exceptional turn down ratios.

The use of a boiler sequencing system ensures that boilers are fired in a controlled manner providing cost savings by preventing individual boilers from over firing and cycling on and off unnecessarily. The sequencer determines the number of boilers required to meet the system demand by monitoring the steam pressure in the header or the steam flow, and keeps the remaining boilers in a warm standby state, allowing them to be brought up to pressure quickly in the event of an increase in demand. The sequencing panel also provides an overview of the boiler plant, displaying the system pressure as well as individual boiler pressures, firing rates and statuses.

Of all the systems in the boiler house, the advanced design Ratiotronic control unit is one of the most important elements for delivering consistent energy savings and emissions reduction. This sophisticated digital control system provides a range of automatic burner management options including control of variable speed drives, fuel and air trims and operations sequencing for precise, real time fuel efficiency.

A boiler control panel incorporating a touch screen and digital burner management system to display and control a variety of burner/boiler equipment.
