This article analyzes the mechanism of formation main components harmful emissions characteristic combustion chambers operating on conventional hydrocarbon fuels. The method a preliminarily prepared depleted air–fuel mixture was chosen as object study. suppressing implemented in design low-toxic chamber developed applied to GT-009 M type unit with impact cooling burner pipe and provides for sta...

Combustion of hydrocarbons with pure oxygen as oxidizer is used, e.g., in high-temperature processes such the partial oxidation (POX) to produce synthesis gas high purity. Due prevailing temperatures, active cooling required for many parts. For laboratory-scale experiments, dimensions key parts are too small conventional manufacturing processes. One example a burner plate especially developed P...

With developing interest in NH3 as a prospective energy carrier, combustor designs and fuelling concepts require optimisation to reduce NOx emissions. Through the introduction of staged concepts, pathways have previously been identified that limit production whilst improving efficiency reducing unburned NH3. However, efficacy secondary air staging is sensitive primary flame behaviour, low emiss...

<span>The purpose of this article is to describe the automation developed by means a programmable logic controller for burner fire tube boiler, in order improve efficiency process generating steam quantified through percentage oxygen generated. The implementation was under control strategy based on use servomotors that allow gradually open or close solenoid valves dose amount air and fuel...

Combustion of pulverized biomass in a laboratory swirl burner is computationally investigated. The two-phase flow modelled by an Eulerian-Lagrangian approach. particle size distribution and turbulent dispersion are considered. radiative heat transfer the P1 method. For modelling turbulence, different RANS approaches applied. pyrolysis solid fuel single step mechanism. combustion volatiles two-s...
