RESEARCH OF THE COMBUSTION PROCESS OF LIQUID FUELS AT THE CHANGE OF THE INJECTED PARTICLE’S VELOCITY
The combustion process of liquid fuel in the combustion chamber on the basis of the solution for differential two-dimensional equations of the turbulent reactive flows has been numerically researched. The influence of the spray velocity on the combustion

Beyond Furnaces: Harnessing In Situ Joule Heating for Efficient C1 Catalysis
Joule‐heated catalysis directly converts electrical energy into localized heat within conductive catalysts, overcoming the heat‐transfer limitations of conventional furnaces. This review summarizes recent advances in C1 molecule conversion, including CO2 methanation, reforming for hydrogen production, and HCHO/CO oxidation, while highlighting ...

A dual‐phase flash Joule heating strategy converts pre‐pyrolyzed biomass into structurally tunable carbon materials from waste feedstocks. By decoupling current‐driven thermodynamic input and duration‐dependent kinetic relaxation, the process maps the transition from amorphous carbon to few‐layer turbostratic graphene and turbostratic nanographite ...

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Methanol With Increased Water Content in Internal Combustion Engines
This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.
