ENER-G has launched a new range of ‘ultra-low’ NOx Combined Heat and Power (CHP) systems (50kWe to 230kWe) which promises a five-fold reduction in emissions.
The technology is achieving emissions levels of less than 50mg/Nm3 @ 5% O2 that are sustained across the lifetime of the emissions system of its new CHP range.
This is almost half of the most stringent emissions limit set by both BREEAM and the new Greater London Authority (GLA) Sustainable Design and Construction guidelines, and five times lower than the more widely accepted limit of 250mg/Nm3 @ 5% O2.
Another highlight of this CHP system is that it achieves the emission reduction without the need for any expensive external NOx abatement technology and without increasing the size or footprint of existing CHP units.
In addition to exceeding the strict new air quality standards necessary to achieve planning permission in the Greater London boroughs, the low-NOx ENER-G CHP fleet will also qualify for maximum credits under the revised BREEAM standard, the company said.
The technology is also fully compliant with the Code for Sustainable Homes and Clean Air Act.
The new CHP range has been cleverly reconfigured using 3D CAD modeling technology aligned with BIM processes to fit existing components into the smaller remaining space.
For CHP systems with an electrical output above 230kWe, ENER-G can incorporate external NOx abatement technology, such as selective catalytic reduction (SCR). This can bring the NOx emissions level down as low as 10mg/Nm3, when necessary.
