BOILERS & BURNERS


Riello adopted 'production islands' in 2020 to streamline the manufacturing process


combustion research centres. By 2004, we had manufactured and sold more than 500,000 burners. In 2020 we updated our production


lines to new production ‘islands’ according to the lean manufacturing principles, which improves our production efficiencies and provides additional flexibility to our burner production capacity. We also tested 100% hydrogen-ready burners to support UK government hydrogen research programmes, such as the Hy4Heat trials; and we recently launched the ULX (Ultra Low NOx) range.


The benefits of burner experience


In the past 30 years, burner technology has advanced to reduce emissions and improve combustion efficiency. Riello’s Graham Barker reflects on achievements and future challenges.

W


hen Pilade Riello founded Riello in Legnago, Italy in 1922, he had no idea that he would one day


be considered one of Italy’s most outstanding entrepreneurs. His innovations in combustion technology have changed the way industries produce heat and hot water; his artisan workshop has evolved from a facility which produced oil burners for bread-baking ovens, to a brand with international presence and a worldwide leader in burner production. Riello celebrated its centenary in 2022, boasting more than 100 years of combustion experience across more than 20 countries. Riello’s UK offices were established in 1992, relocating from an agency in Birmingham to an official Riello subsidiary based in Huntingdon, Cambridgeshire.

Advancing years Our product portfolio has expanded from residential and low-power commercial burners to becoming a leader in residential burners and supplying high-power industrial burners up to 80MW. Burner technology has evolved significantly, with an emphasis on reducing emissions whilst increasing combustion efficiency. As an example, gas burners have now evolved into low NOx gas burners to satisfy evolving market and regulatory requirements. Continued R&D programmes help us develop market-leading combustion technologies such as our new patented ULX (Ultra Low NOx) combustion head that can offer NOx


emissions lower than 40mg/kWh without any external recirculation requirements. We are also at the


forefront of renewable liquid fuel research and development, including new fuels derived from waste fats


The RS810E BLU – a modular monoblock structure means all necessary components are combined in a single unit


and used cooking oils (UCO) such as Hydrotreated Vegetable Oil (HVO). We have been working closely with our leading residential OEM oil boiler customer base to provide full test programs and burner specifications. In the UK, we have always prioritised


a ‘customer-first’ approach. We enjoy strong customer relations with core brand values, centred on innovation and excellence, along with a commitment to swift responsiveness.


Proudest achievements Notable achievements include the expansion of our Combustion Research Centre, located in Angiari, Italy, which tripled in size in 2001 and is now one of the leading global


Overcoming industry challenges The electrification focus of the off- grid housing stock for the net zero target by 2050 poses a significant challenge. We as a company are working closely with industry bodies such as OFTEC and UKIFDA – as well as our residential boiler manufacturing customers – to support the inclusion of renewable liquid fuels (HVO) in government plans. HVO can provide instant carbon savings of approximately 88% when compared to current fossil fuel oils, such as kerosene, as the carbon impact has been accounted for in the waste oils’ previous lifecycle. With the recent delay of the


proposed oil boiler ban from 2026 to 2035, it appears that the government accepts a technology neutral approach to achieve required targets. The off-grid sector can help the government achieve its requirements to reduce carbon emissions by supporting renewable liquid fuels in place of current fossil fuel oils. The biggest obstacle currently is


the cost – HVO is seen as a road fuel, so it has duty and tax applied by the government. This is currently being discussed within the government and we, as an industry, are hopeful of a positive outcome regarding taxation and duties being reduced.


Looking ahead At Riello, we anticipate a transition in the residential market to renewable heating oils and foresee the commercial and industrial sector evolving to include hydrogen burners, with continued emphasis on emission reductions for natural gas burners. The company remains committed to being the customers' first choice burner partner, embracing renewable fuels and supporting global emission reduction targets. ■
