焦爐煤氣發電機組做為焦化備用電源的特點

焦爐煤氣是焦化產業的主要副產品之一,每煉一噸焦炭會產出300-350m3左右的焦爐煤氣,焦爐煤氣約40%-50%用于回爐燃燒,其余剩余煤氣必須使用專門回收裝置進行回收利用,否則只能燃燒排放大氣。一些小的企業,由于煉焦產生的焦爐煤氣量較少,投資甲醇、化肥等其他項目可能還達不到規模,成本優勢不明顯,因此用于焦爐煤氣發電是一種投資小、見效快的一種有效途徑。
D88尊龙Coke oven gas is one of the main by-products of the coking industry. Every ton of Coke will produce about 300-350 m3 coke oven gas. About 40-50% of coke oven gas is used for burning in the furnace. The rest of the gas must be recycled by special recovery devices, otherwise it can only be burned and discharged into the atmosphere. Some small enterprises, because coking produces less coke oven gas, investment in methanol, fertilizer and other projects may not reach the scale, cost advantage is not obvious, so the coke oven gas power generation is a small investment, effective way.

2. performance characteristics of internal combustion coke oven gas generating set
焦爐煤氣內燃機發電機組的工作原理與汽車發動機工作原理相似,需要用火花塞點火,由于內燃機汽缸內工作溫度達到14000?使其效率大大超過了蒸汽輪機和燃氣輪機,發電效率達到35%以上。其特點為:
The working principle of the coke oven gas internal combustion engine generator set is similar to that of the automobile engine. It needs to be ignited by spark plug. The efficiency of the internal combustion engine is much higher than that of the steam turbine and gas turbine because the working temperature in the cylinder reaches 14 000? And the power generation efficiency is more than 35%. Its characteristics are:
2.1結構緊湊,體積小占地少。
2.1 compact structure, small volume, less occupation.
2.2熱效率高,相比較蒸汽輪機和燃氣輪機高10%以上。
2.2 the thermal efficiency is high, which is 10% higher than that of steam turbine and gas turbine.
2.3操作簡便,起動快捷。
2.3 easy operation and quick start.
2.4規模可選擇范圍較寬,幾臺或十幾臺并機均可。
2.4, the scope of selection can be wider and several or more machines can be used.
2.5由于工藝簡單,投資較少可進行自動化控制。
2.5 because of simple process and less investment, automatic control can be carried out.
我公司于2010年底購入江蘇南通產BG12V190DJ型煤氣內燃發電機組3套,于2011年并網發電后一直運行穩定,發電功率達1500KW左右,每年可節省用電占全年用電的30-40%,為企業創造了可觀的經濟效益。
At the end of 2010, our company purchased 3 sets of BG12V190DJ gas-fired internal combustion generating units from Nantong, Jiangsu Province. They have been running steadily since they were connected to the grid in 2011. The power generation power reaches 1500KW or so, which can save 30-40% of the annual electricity consumption and create considerable economic benefits for the enterprises.

3.1焦爐煤氣內燃機發電機組在組成內部局域供電網絡后,在總配電室低壓總開關處安裝并網同期裝置一套,通過同期裝置和市電低壓并網后可供企業內部使用。
3.1 After the coke oven gas internal combustion engine generator set is composed of an internal local power supply network, a set of synchronization device is installed at the low-voltage main switch of the main distribution room, which can be used by the enterprise after the synchronization device and the low-voltage power supply of the market are connected to the grid.
3.2在總配電室低壓總開關處安裝逆功率保護模塊一套,可防止外網停電時發電機所發電力反送入市電電網造成事故。
3.2 Installing a set of inverse power protection modules at the low-voltage main switch of the main distribution room can prevent the power generated by the generator from being sent back into the municipal power grid when the external power grid is cut off.
3.3當外網停電時,低壓總開關通過逆功率模塊控制斷路器跳開,發電機變成孤網運行,保證風機、循環氨水泵等主要設備不斷電而正常運行;可避免焦爐因停風機而產生的煙火污染,如功率足夠大也可保證焦爐的正常生產。
3.3 When power failure occurs in the external network, the low-voltage main switch controls the circuit breaker to jump through the reverse power module, and the generator turns into an isolated network to ensure the normal operation of the main equipment such as blower, circulating ammonia pump and so on. It can avoid the pyrotechnic pollution of the coke oven caused by blower shutdown, and if the power is large enough, it can also ensure the normal production of the coke oven.
3.4當外網再次供電時,可通過總開關處同期裝置再次并網繼續運行。
3.4 when the external network is powered again, it can be connected to the grid again through the main switch.
3.5發電機組可通過程控機軟件實時監控發電機組的各種溫度、壓力、電壓、電流等參數和自動調節煤氣、冷卻水等流量,保證發電機組的正常運行
D88尊龙3.5 Generator Set can monitor all kinds of temperature, pressure, voltage, current parameters and automatically adjust gas, cooling water and other flow through the program-controlled computer software to ensure the normal operation of the generator set.
