【摘要】：微型熱電聯(lián)產(chǎn)系統(tǒng)是一種小型化的能源轉(zhuǎn)換裝置。它能夠在一個(gè)緊湊的系統(tǒng)中將天然氣、LPG或者其他形式的燃料同時(shí)轉(zhuǎn)化為電和熱，這提高了能源的利用效率，對(duì)節(jié)能減排、實(shí)現(xiàn)“十二五”能源規(guī)劃目標(biāo)具有重要意義。 對(duì)中國(guó)不同氣候帶的5個(gè)典型城市（長(zhǎng)春、北京、西安、上海和廣州）的典型家庭在使用4種微型熱電聯(lián)產(chǎn)產(chǎn)品（Ene-Farm、Ene-Farm type S、Ecowill、WhisperGen）時(shí)兩者的匹配程度、CO2減排量以及家庭的經(jīng)濟(jì)收益情況進(jìn)行了分析。考察了在不同電價(jià)格、燃?xì)鈨r(jià)格和微型熱電聯(lián)產(chǎn)產(chǎn)品價(jià)格的情況下，這幾個(gè)城市典型家庭在使用典型微型熱電聯(lián)產(chǎn)產(chǎn)品時(shí)的經(jīng)濟(jì)收益和投資回收期。結(jié)果指出，微型熱電聯(lián)產(chǎn)產(chǎn)品與中國(guó)普通家庭傳統(tǒng)的能源獲取方式相比能夠在很大程度上減少CO2的排放；在當(dāng)前電價(jià)格、燃?xì)鈨r(jià)格、采暖價(jià)格和微型熱電聯(lián)產(chǎn)產(chǎn)品價(jià)格的情況下，微型熱電聯(lián)產(chǎn)產(chǎn)品與傳統(tǒng)的能源獲取方式相比價(jià)格太過(guò)昂貴，各城市典型家庭對(duì)微型熱電聯(lián)產(chǎn)產(chǎn)品的目標(biāo)價(jià)格大多介于5000-15000元/kWe之間，這個(gè)價(jià)格與美國(guó)能源部預(yù)期的價(jià)格基本吻合；微型熱電聯(lián)產(chǎn)系統(tǒng)價(jià)格、電價(jià)格和燃?xì)鈨r(jià)格對(duì)經(jīng)濟(jì)節(jié)約指數(shù)和投資回收期有重要影響。微型燃料電池?zé)犭娐?lián)產(chǎn)系統(tǒng)的價(jià)格越高、燃?xì)鈨r(jià)格越高，，投資回收期越長(zhǎng)，經(jīng)濟(jì)收益越�。浑妰r(jià)越高，系統(tǒng)的投資回收期越小，經(jīng)濟(jì)收益越大。 將天然氣制氫單元、CO脫除單元、燃料電池組件、余熱回收單元和輔助單元等集成為一臺(tái)微型燃料電池?zé)犭娐?lián)產(chǎn)系統(tǒng)樣機(jī)。測(cè)試了該樣機(jī)的啟動(dòng)時(shí)間、典型操作條件下的合成氣組成以及系統(tǒng)的電效率、熱效率和總效率，并將該樣機(jī)與微型熱電聯(lián)產(chǎn)產(chǎn)品Ene-Farm和Ene-Farm type S進(jìn)行了比較。測(cè)試結(jié)果顯示樣機(jī)可以在1小時(shí)內(nèi)啟動(dòng)；合成氣中CO濃度小于10ppm，能夠滿足燃料電池對(duì)合成氣的需求；樣機(jī)的電功率為200W、熱功率為530W、電效率為15.4%、熱效率為40.9%；與日本的兩款已經(jīng)上市的微型熱電聯(lián)產(chǎn)產(chǎn)品相比，在技術(shù)指標(biāo)上該樣機(jī)還有很大差距，但是在價(jià)格上本樣機(jī)有很大的優(yōu)勢(shì)。
[Abstract]:Micro cogeneration system is a miniaturized energy conversion device.It can convert LPG or other forms of fuel into electricity and heat simultaneously in a compact system, which improves the efficiency of energy utilization, and is of great significance to energy conservation and emission reduction, and to the realization of the energy planning target of the 12th Five-Year Plan.Five typical cities with different climatic zones in China (Changchun, Beijing, Xi'an,A typical household in Shanghai and Guangzhou analyzed the matching degree of the two products and the amount of CO2 emission reduction and the economic benefits of the household when using four miniature cogeneration products (Ene-Farm-Farm type Scowillery / Whisper Gen).Under the conditions of different electricity price, gas price and micro cogeneration product price, the economic income and investment payback period of these typical families in using the typical miniature cogeneration products are investigated.The results show that, compared with the traditional energy access methods of ordinary Chinese households, micro cogeneration products can greatly reduce CO2 emissions, and at current electricity prices, gas prices,In the case of heating prices and the prices of micro-cogeneration products, the prices of micro-cogeneration products are too high compared with traditional energy acquisition methods.Most of the target prices for micro-cogeneration products for typical households in each city range from 5,000 to 15,000 yuan / kWe, which is basically in line with the price expected by the US Department of Energy; the price of the mini-cogeneration system is basically in line with that of the US Department of Energy.Electricity price and gas price have important influence on economic saving index and investment payback period.The higher the price of the micro fuel cell cogeneration system, the higher the gas price, the longer the investment payback period, the smaller the economic return; the higher the electricity price, the smaller the investment payback period and the greater the economic benefit.The CO removal unit, fuel cell assembly, waste heat recovery unit and auxiliary unit of natural gas hydrogen production unit are integrated into a miniature fuel cell cogeneration system prototype.The start-up time of the prototype, the composition of syngas under typical operating conditions, and the electrical efficiency, thermal efficiency and total efficiency of the system were tested. The prototype was compared with Ene-Farm and Ene-Farm type S, a miniature cogeneration product.The test results show that the prototype can be started within 1 hour, and the CO concentration in the syngas is less than 10 ppm, which can meet the demand of the fuel cell for the syngas.The electric power of the prototype is 200W, the thermal power is 530W, the electric efficiency is 15.4W, and the thermal efficiency is 40.90.Compared with the two mini cogeneration products that have been put on the market in Japan, there is still a big gap in the technical index of the prototype, but the prototype has a great advantage in price.
