Services - Biomass Boiler Analysis
With gas and electricity bills climbing year-on-year, many people are turning towards alternative heating solutions such as biomass boilers. This
growth in uptake has been accentuated by the introduction of the Renewable Heat Incentive in 2011, with the government providing subsidies over a
period of 20 years to improve the financial viability of the systems.
By the end of 2013, the government intends to introduce emissions criteria into the RHI tariff scheme, with the exhaust gas from boilers containing no more than 30g/GJ of particulates and 150g/GJ of nitrous oxide. Alongside this, the government also intends to introduce energy efficiency limits on the RHI payments, to ensure boiler performance is suitably high to prevent misuse of energy resources.
In partnership with Mercia Energy, WISenvironmental has the capability to monitor both flue gas emissions and the heat efficiency of the boiler to meet these incoming criteria; WISenvironmental can also use its monitors to investigate technical problems with the boiler or heat transmission service and propose solutions with the assistance of Mercia Energy.
Biomass Boiler Heat Balance
WISenvironmental was commissioned by Mercia Energy to perform a Heat Balance Calculation on one of a number of biomass boilers installed in 2009.
The boiler owner was concerned that the biomass boilers supplied and commissioned were running below their expected efficiency range of around 90%.
To validate this claim WISenvironmental performed a test run to monitor the boiler's performance and verify whether these concerns were real or
perceived. The exercise not only confirmed that heat losses were occurring, but it also identified the location of the main heat loss.
The client was able to target the problem area, which ultimately resulted in improved efficiency.
