In order to improve efficiency of vehicle engine,a combustion condition analysis system of vehicle engine with multi-cylinder was developed using Visual Basic6.0 software under cylinder pressure monitoring.
At the same time, in order to draw a complete conclusion, we should gather the information on the formation procedure of coalrock, the characteristic of fragmentation system, the distribution of mineral within the feed coal and the combustion condition.
Incorporated with the analysis of boiler style and actual combustion coal of the 480t/h boiler in Donghai power station, modified means are provided and applied. Unit must to be shut down because of cleaning slag is avoided, combustion condition is ameliorated, flue gas temperature is decreased and the boiler efficiency is improved, the power station acquires vast economic utility.
By means 0f sample combustion in testing table of coal pulverized combustion,the combustion condition of existing boiler is simulated,and the slaggingcan be exactly predicted. The criterions for reforming design of 200MW unit boiler burners in Tongliao power plant are provided.
The choice principles of a primary air fan(PAF) are described. An efficiency decrease of 57.89% and the worse of the combustion condition in furnace arose from the shortened blades in the PAF for the pulverized coal positively feeding system in 350MW thermal power plant.
Measurement and analysis are made on coal powder distribution of the former Czechoslovakia made 650 t/h boiler's primary air pipe and burner,and investigation for its influence on combustion condition is made.
The spectrum temperature is higher 100~700℃than the thermocouple temperature. Once combustion condition being worse, the thermocouple temperature became lower, and the flame spectrum temperature became higher and the temperature fluctuation increase too.
A study of nitrous oxide decomposition over calcium oxide in combustion condition
The initial and final attrition rates during combustion were higher than those in the non-combustion condition, because the heat and thermal shock were produced to increase attrition rate during incineration.
An abrupt transition was observed between a condition of "passivation," in which a thin film of SiO2 formed at low temperatures, and a steady-state "combustion" condition at high temperatures.
The improved magnetic properties are accounted for by the enhanced iron oxidation at a given combustion condition.
The mathematical models of turbulent jet flame under the highly preheated air combustion condition are conducted in the paper.
