چکیده
Abstract In order to reduce carbon emissions, enhance the operational flexibility of gas turbine power plants, and fill gap in practical engineering transformation natural gas-hydrogen blended combustion heavy-duty turbines, a hydrogen blending retrofit was conducted on an F-class combined heat unit. This served examine problems chamber tempering, pulsation, NO x emission increase caused by direct hydrogen-doped chamber. this paper, body mixing system were reformed respectively. Retrofit schemes proposed that suitable for two operating conditions: 5%–15% 15%–30% blending. Experimental tests as means evaluating performance retrofitted its compatibility with boiler steam turbine. The results showed there be stable combustion, no significant average burner temperatures or occurrence flashback. output mostly remained unchanged emissions met regulatory standards. waste flue temperature controlled within range 84.9–88.2 °C, meaning safe operation not affected. rate 0.2 Vol%/s, which indicates smooth precise control process. It estimated annual reduction CO 2 would 11,000 tons 28,400 following respective at 15% 30%. A reliable scheme turbines based is presented study, has reference value.

Transient combustion control of internal combustion engines
This thesis addresses the problem of combustion control for automotive engines. A method is proposed to complement existing controllers, which use lookup tables based on steady-state operation. During transients, the new control method adjusts fast control variables (ignition or injection time) to compensate for deviations in the cylinder initial conditions from their optimal values due to the ...
متن کاملThe effect of hydrogen and nitrogen addition on heavy duty diesel engine emissions under reactivity controlled compression ignition combustion
The aim of this study is to evaluate a heavy duty diesel engine operation under reactivity controlled compression ignition combustion fueled with diesel oil and natural gas enriched with hydrogen and nitrogen addition. In this study, a single cylinder heavy– duty diesel engine is set to operate at 9.4bar gross IMEP (Mid- Load). The amount of injected diesel oil per cycle into the engine combust...
متن کاملLow Emission Combustion Technology for Stationary Gas Turbine Engines
The need to control exhaust emissions from stationary power sources is dictated by environmental regulations that limit the amount of smoke (particulates), sulfur dioxide, carbon monoxide, hydrocarbons, and oxides of nitrogen or NOx that can be exhausted into the atmosphere. In areas where atmospheric pollution is a serious concern, as in the Los Angeles basin, very low emission levels are dema...
