An oil preheater is a unit or a component that warms fuel oil to reduce its viscosity. The oil preheating process is used, for example, when firing heavy oils as the viscosity of those oils is not suitable for atomisation by the burner nozzles. Light fuel oil is also preheated for low capacity burners, e.g. the WL5-purflam®, so that the fine atomisation of the oil can be ensured even after long periods of inoperation or in low ambient temperatures. The advantages arising from that are a lower fuel throughput (and therefore lower ratings), improved combustion with reduced emissions and an improved burner start.
Oxygen trim (O2 trim)
An O2 sensor or probe is used to measure combustion quality. When the quality deviates, small adjustments are made to compensate. In this way, emissions are reduced and combustion quality and efficiency are maintained at the highest level. For larger burner systems O2 trim reduces fuel consumption and thus fuel costs. Note: Larger burners use an O2 sensor, ionisation electrodes are used for the WTC condensing boiler.
O2, oxygen, is a colourless, odourless, tasteless gas. It forms approximately 21 % of air. Oxygen is an indispensible component of the combustion process.
