Conventional boilers. If your hot water tank has a thermostat, set it between 55°C and 60°C. Then you can adjust your boiler temperature to maximise energy efficiency: In winter, set the boiler temperature control to max (80°C). In summer, when you dont need the heating, set it somewhere in the middle (55°C-60°C).

Boiler Efficiency Testing Objectives

Boiler Efficiency Testing Kiwa Gastec is a Notified Body (0558) under the Boiler Efficiency Directive. We test gas, solid fuel and oil-fired boilers to help you to demonstrate compliance with European efficiency requirements. The Boiler Efficiency Directive covers all domestic boilers fuelled by gas and/or oil.

Smoke emission and control of fuel gas boiler - Ningbo

One method to reduce NOx levels from boilers firing distillate oils is through the use of low nitrogen fuel oil. Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound nitrogen). When low NOx oil is fired in firetube boilers utilizing flue gas recirculation, NOx reductions of 60%-70% over NOx emissions from standard No. 2 oils have been

Experimental investigation on flue gas emissions of a

23/02/2010 · Owing to the low sulphur and low nitrogen contents of many biomass materials, substituting biomass for fossil fuels, particularly coal, can reduce SO x and NO x emissions. This study investigated flue gas emissions, particularly carbon monoxide and nitrogen oxides, of a domestic biomass boiler under various operating conditions.

Boiler efficiency testing Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilized to generate steam. There are two methods of assessing boiler efficiency: 1) Direct Method: In this method the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.

26/09/2018 · From 26 September 2018, under EU regulation No 814/20133, emissions of nitrogen oxides expressed in terms of nitrogen dioxide from water heaters should not exceed 56mg·kWh¹. Natural gas boilers with outputs typically between 500kW and 32MW provide a good opportunity for flue gas recirculation (FGR) (Source: Bosch)
