當焦炭推上攔焦車進入熄焦器后，立即關閉罐蓋，同時啟動真空泵、冷凍機、高壓循環水泵，這時，燃燒著的焦炭就會因真空泵把熄焦器內抽成負壓，由於缺氧，使焦炭熄滅，雖然煤炭在瞬間被熄滅，但由於焦炭生成過程中所產生的大量的熱量還存在，這時，冷凍機和夾層中的循環水的工作就會把焦炭中的熱量帶走，使之在短時間內將溫度降到60以下，在這種狀態下把焦炭從熄焦器內推出入庫，焦炭就不會復燃。Using the traits of arc adjust itself of the co _ 2 welding, adopting slow - descending feature or even feature of electrical source equipping with system that delivering the welding rod at the invariable speed, then, the arc burning steadily is realized, and the quality of welding is improved

結果表明：二次流流量隨著一次流流量的增加而增加，由於二次流流量的增加速度低於一次流，引射系數減小；在純擴張式結構實驗中，引射燃燒室壓強很低，難以實驗推力增強；二次噴管改變了引射燃燒室的壓強分佈，降低了引射系數，改善了混合狀況能；對于本文的實驗結構，存在一個最優的二次噴管出口面積，使引射火箭推力最大，同數值模擬結果相吻合。A parametric study of the effect of variation in injection timing is then carried out. both the simulation results and experimental data show that deferred injection timing leads to decreases in combustion pressure and nox concentration
模擬結果和實驗結果都表明，推遲噴油，可以減少預混燃燒所佔的比例，降低最大燃燒壓力，從而減少直噴式柴油機的no _ x排放。Characters including : fuel atomization device replaced by gas sprayer, gas supply controlled by gas flux valve ; separate fuel supply from combustion - supporting air, regulate air supply through changing the electioneering voltage to make the fully burning and improve efficiency and reduce fuel consume ; arts and crafts are simple, the modification of the oil heater ' s configuration is little and the heating power is not below the oil heater ' s level ; because of falling the voltage of electioneering, greatly descend the noise of the sample machine compared with the original
其特點是：以燃氣噴頭替代原機燃油霧化裝置；以燃氣流量控制閥控制燃氣的供給；燃氣的供給與助燃空氣的供給相分離；通過改變主電機的電壓，調整空氣的供給量，使燃燒更加充分完全，並進一步提高了熱效率，降低了燃料消耗；工藝簡單，對原機型改動較小；樣機的加熱功率不小於原機型水平；此外，由於主電機電壓的降低，使樣機的整機噪聲比原機大大下降。Now design efficiency of common gas boiler can reach 90 percent or so, but various factors such as load, fuel quality, work condition and pressure which result in uncompleted burning of gas and excess air, decrease boiler hot efficiency and cause resources waste and environment pollution. considering these it is essential to adopt closed loop feedback control to boiler burning system
現今，一般的燃氣鍋爐設計效率均能達到90 %左右，但在實際運行中，因負荷、燃料品質、工作環境、壓力、混合情況等因素的影響，往往造成燃氣不完全燃燒或空氣過量，使鍋爐熱效率降低，造成能源浪費與環境污染，在這樣一種背景下，有必要對其燃燒系統進行閉環反饋控制。To reduce the mechanistic load and thermal load of rta52l " type marine low speed diesel engines, the paper also discuss about the chosen, optimize and energy saving regarding compress ratio, the maximum combustion compress and other main parameters
