(PDF) Fouling of Heat Transfer Surfaces - ResearchGate
Oct 19, 2009 · Fouling in a boiler heat transfer surface is different from slagging. Even though both affect heat transfer, fouling happens in the convection heat transfer surface in boiler and slagging happens in the radiant area. Both are results of inorganic material in the fuel. The causes for fouling are mainly due to the low melting point of alkaline constituents of the inorganic …Learn More
Comments on good or bad indoor pellet boilers | Hearth.com
Our boilers include a Lambda sensor in the exhaust of the boiler to measure the oxygen levels of the exiting flue gases. This allows the boiler to fine-tune the amount of air the fan mixes into the combustion chamber, taking into account variations in pellet quality, changes in the draft, and the dirtiness of the boiler.Learn More

(PDF) Effects of fouling on the efficiency of heat
Heat exchanger fouling is a common problem in lignite utility boilers that leads to a reduction in heat transfer efficiency. An interesting evaluation of the economics of fouling can be found in [l]. In order to achieve the desired insight about the fouling phenomenon, a numerical model was developed to predict the mechanism of ash deposition Learn More
An overview of problems and solutions for components
Dec 21, 2017 · Fouling in boilers is caused due to reduction in heat transfer, which further leads to sufficient loss of superheat and hot flue gas temperatures [43, 44]. Major factors that lead to the removal of fouling are the deposit strength and the adhesive bonding between the heat transfer surface and ash deposit.Learn More
