Stratton mk2 wall hung boiler - Hamworthy Heating
Testimonials. Choosing two Stratton 150kW wall hung boilers was an obvious choice for our temporary plant rooms due to their high turndown ratio, stainless steel heat exchangers, spark ignition, and C13 flue systems. The BMS 0-10V interface built into the boiler controls platform enables us to monitor remotely. Stuart Giles, Giles Heating.

US7430969B2 - Method for reducing the amount of a sulfur
A process for removal of sulfur dioxide from a flue gas. An alkaline admixture is coated with a coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone and results in a coated alkaline admixture. The coated alkaline admixture is introduced to the boiler to create a reaction that reduces the amount of sulfur dioxide from the flue gas.
