Despite the stochastic nature of the process, as well as the challenges involved in measuring such a phenomenon, combustion deposit
flaking has been reported in literature.
"We study their application and the major factors causing wear, and set up the most appropriate test module simulating the amount of sliding, normal contact load, combustion deposit
factor and temperature to recreate that problem.
Consequently, the increase in particulate emissions measured can be directly connected to the combustion deposit
In addition to durability issues with thermocouples and wires, combustion deposits
that can accumulate on the piston surface tend to bury the thermocouple junctions.
The tenacity and strength of biomass combustion deposits
tend to be higher than for deposits from coal combustion, with smooth deposit surfaces and low porosity.
