The image shows the 1.5 tons/hour vertical steam boiler was used at the Russian. The customer's original boiler was outdated, unable to provide sufficient heat, and had increased fuel consumption, so they decided to replace it with a new boiler, and  customer provided us with images of the boiler room space, and we recommended several vertical boiler models. Ultimately, the Russian customer placed an order for one LHS gas-fired oil boiler to replace the outdated boiler. The customer reported that the new boiler saves 20% in fuel compared to the old one!
