The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
When the ErP Directive was introduced back in September 2015 so too were limits on the emissions for and all other fuels As a result appliances became mandatory At the time the UK gained an exemption because of its status as being not just a country relying on a significant volume of boilers but also the only user
· August 12 2019 Achieving below 30mg is possible says SAACKE Development & Process Engineer Dr Ing Christopher Rosebrock Revised emissions standards published by the EU in 2017 will impose a significant reduction in for large (over 50 MW) The exact values will be transposed into national law by 2021 although the mandatory limit
In addition emulsified -sulfur heavy (HFO) with a 20 vol% water content and pure -sulfur HFO were used as fuels for burning in an industrial under normal operating conditions
Since 20th December 2018 medium combustion plants (excluding plants and turbines) for new buildings which commercial boilers fall under with a thermal input between 1MW to 50MW must stay below emissions of 100mg/NM³ () or 200mg/Nm³ () All of Hamworthys /air premix boilers are below these levels and have been tested in accordance with this standard
In September 2018 a mandatory maximum emissions level of 56mg/kWh for and LPG boilers and 120 mg/kWh for -fired boilers was imposed but for some local authorities its not enough and they are demanding ultra- boilers with a maximum emissions level of 30mg/kWh
