The industrial combustion chamber designed for burning low-calorific syngas from gasification of waste biomass is presented. For two different gases derived from gasification of waste wood chips and turkey feathers the non-premixed turbulent combustion in the chamber is simulated. It follows from our computations that for stable process the initial temperature of these fuels must be at least 800 K, with comparable influx of air and fuel. The numerical simulations reveal existence of the characteristic frequency of the process which is later observed in high-speed camera recordings from the industrial gasification plant where the combustion chamber operates. The analysis of NO formation and emission shows a difference between wood-derived syngas combustion, where thermal path is prominent, and feathersderived fuel. In the latter case thermal, prompt and N 2 O paths of nitric oxides formation are marginal and the dominant source of NO is fuel-bound nitrogen.

This paper presents an experimental and numerical study of the impact of various additives on the oxidation of a typical automotive surrogate fuel blend, i.e. n-heptane and toluene. It examines the impact of engine re-cycled exhaust gas compounds on the control of a Homogeneous Charge Compression Ignition (HCCI) engine. A series of experiments were performed in a highly diluted Jet-Stirred Reactor (JSR) at pressures of 1 and 10atm (1atm = 101325Pa). The chosen thermo-chemical conditions were close to those characteristic of the pre-ignition period in an HCCI-engine. The influence of various additives, namely nitric oxide (NO), ethylene (C 2 H 4 ) and methanol (CH 3 OH), on the oxidation of a n-heptane/toluene blend was studied over a wide range of temperatures (550-1100K), including the zone of the Negative Temperature Coefficient (NTC).A new detailed chemical kinetic reaction mechanism is proposed for the oxidation of the surrogate fuel. It includes reactions of NO, methanol (CH 3 OH) and ethylene (C 2 H 4 ) and is used to explain the obtained experimental data. The mechanism is further used to theoretically study the impact of other Exhaust Gas Recirculation (EGR) compounds on the hydrocarbon oxidation, namely ethane (C 2 H 6 ), formaldehyde (HCHO) and carbon monoxide (CO).

“…Those functions are the basis of the species thermodynamic description; for many species, they are either tabulated, or approximated with polynomials. In the current research, they are taken from [7]; their format (two temperature interval) is described in [8] and [9]. We joined those temperature intervals into a single, and obtained the polynomial coefficients using the linear regression analysis based on the least squares technique.…”

A rotating detonation engine (RDE) combustion chamber was modeled in the work numerically using 3D geometry. The RDE is a new type of engines capable to create higher thrust than the traditional ones, which are based on the combustible mixture deflagration process. In the numerical experiment, different scenarios of the engine performance were obtained. The calculations were made at a compact supercomputer APK-5 with a peak performance of 5.5 Tera Flops.
