Problems solved by technology

[0003] Analyzing the gas composition of hydrocarbon fuels is an important pre-step to optimize combustion conditions and reduce negative impacts on the environment. The solution for rapid analysis of the gas components of hydrocarbon fuels can only be analyzed after collecting the gas in repeated experiments. The cost of the experiment is high and the analysis efficiency is low.

Description

technical field [0001] The invention relates to a system for measuring and calculating components of hydrocarbon fuel combustion thermal dissociation gas. Background technique [0002] Hydrocarbon fuel is a compound mainly composed of carbon element C and hydrogen element H. The core of the thermal power system using hydrocarbon fuel is to mix hydrocarbon fuel with air, burn it to obtain heat energy, and then convert it into output power such as kinetic energy or mechanical energy. The combustion product produced by the combustion of hydrocarbon fuel and air is high-temperature gas, and its composition determines the thermophysical properties of the gas and the performance of the thermodynamic system. Gas entering the atmosphere will become a factor affecting detection or the environment. [0003] Analyzing the gas components of hydrocarbon fuels is an important pre-step to optimize combustion conditions and reduce negative impacts on the environment. In the repeated expe...
