Setting the boiler to burn with excess oxygen is the normal solution to reducing emissions. SSTs Zirconium Dioxide oxygen sensors can help customers optimise their boiler combustion efficiency within the oil, coal, gas and biomass boiler market. Results of incorrect combustion include fuel waste, an increased level of toxic emissions and potentially damaging the combustion system.
Oversized boilers are usually too large to meet the lower loads encountered in spring, summer and autumn in any application that does not require 24-hour heating. For much of the year, the load on a building is no more than 30% of the winter peak load, so with boiler turndown ratios of between 3:1 and 4:1 a boiler sized on peak load will spend much of its operating life in slumber mode or switched off.
A well designed and properly operated biomass boiler which is burning the biomass fuel specified by the manufacturer should not produce any smoke, however black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2); The temperatures needed to ensure
17/10/2018 · A Biomass boiler needs 3 main things to create a flame. Fuel Pellets, woodchip or logs. Do you have fuel and is the fuel ok? (make sure it is not wet or too dusty) make sure the fuel is getting to the point where heat and air are supplied (see below description). Air Supply All fire needs a good supply of air (oxygen) to it. Are the
03/09/2019 · The main cause in pellet boilers is if the fuel is too dusty, which can be the result of the pellets being delivered to the fuel store at too high a velocity by the fuel delivery company. Getting the correct flue draught through the biomass boiler is fundamental to achieving good combustion.
Understanding why biomass boilers fail CIBSE Journal
a) Boiler is too large for the heat demand it is supplying Biomass boilers are designed to run for extended periods. When a biomass boiler is too large it only needs to fire for a very short time
