Based on analyzing the influence factors and coupling relations of coke oven gas collector , pid control , decoupling control and expert control are used to control gas collector pressure 摘要集氣管壓力的穩(wěn)定影響焦炭的質(zhì)量和焦?fàn)t的壽命,通過分析焦?fàn)t集氣管壓力影響因素及其耦合關(guān)系,采用pid控制、解耦控制、專家控制來進行集氣管壓力的控制。
The power - generation technology by using coke oven gas baa been introduced , and the technological process , the desulfuration mechanism , and the reactor design etc . concerning purification of coke oven gas and other industrial tail gas for power generation being discussed 摘要介紹焦?fàn)t煤氣發(fā)電技術(shù),并就焦?fàn)t煤氣和其它工業(yè)尾氣的凈化與發(fā)電過程中涉及到的工藝流程、脫硫機理、反應(yīng)器設(shè)計等進行了探討。
An economic and technological comparison is made of methanol units based on anthracite , coke oven gas and bituminous coal , the conventional process is adopted , and the whole unit is optimized , thereby lowering the production cost of methanol , with remarkable competitive superiority on the market 通過對以無煙煤、焦?fàn)t氣、煙煤為原料甲醇生產(chǎn)裝置的經(jīng)濟技術(shù)對比,采用傳統(tǒng)工藝并對全裝置進行優(yōu)化,可以降低甲醇生產(chǎn)成本,在市場中仍具有顯著的競爭優(yōu)勢。
As a system characterized in inertia , delay and nonlinear parameter distribution , the heating furnace can be used in continuous and batch heating with a variety of fuels such as blast furnace gas , coke oven gas , reactor gas , natural gas , heavy oil etc . due to the fact that the heat status inside the furnace is hard to be predicted , many important parameters like bloom temperature distribution can hardly be detected on - line and the furnace type and process parameters are complicated as well , the technology of process control on heating furnace has not been further developed 加熱爐是一個具有大慣性、純滯后和分布參數(shù)非線性的系統(tǒng)。使用的燃料品種繁多,有高爐煤氣、焦?fàn)t煤氣、發(fā)生爐煤氣、天然氣、重油等,其加熱方式有連續(xù)式和批量式,爐內(nèi)的熱狀態(tài)變幻難測,鋼坯溫度分布等許多重要參數(shù)難以直接在線檢測,爐型結(jié)構(gòu)和工藝參數(shù)復(fù)雜。這些因素一直阻礙著加熱爐過程控制技術(shù)的進一步發(fā)展。
