Overview
Riello RX250 S.M ULN Ultra-Low-NOx Gas Burner at a glance
The Riello RX250 S.M ULN is a high-capacity modulating gas burner in Riello's ultra-low-NOx RX programme, aimed at plants where emissions limits are tight and load swings are wide. Its mixing head and gas/air ratio are tuned for the ULN class, and the S.M electronic management modulates output continuously rather than stepping. Large hot-water and steam boilers, plus process heaters, specify it when a standard RX burner would breach local NOx caps. We confirm the boiler's gas input and the site's NOx limit, then set the modulation band so the burner holds stable combustion across the whole operating range.
