Using coking gas power generation technology to fully solve the problem of gas emission in coking plant, coking gas power generation units reduce environmental pollution, protect the ecological environment, reduce production costs, and achieve better economic and social benefits.

有幾家設(shè)計(jì)院給我們做了幾個(gè)焦化的可研，他們提到焦炭與焦?fàn)t煤氣的量。

Several design institutes have done some coking feasibility studies for us. They mentioned the amount of coke and coke oven gas.

1、420Nm3焦?fàn)t氣/t焦炭，其中48%回焦?fàn)t，剩余52%化產(chǎn)。

1. 420nm3 coke oven gas / T coke, of which 48% is recycled and the remaining 52% is produced.

2、393Nm3焦?fàn)t氣/t焦炭，其中42%回焦?fàn)t，剩余58%化產(chǎn)。

2. 393nm3 coke oven gas / T coke, of which 42% is recycled and the remaining 58% is produced.

從其他資料查得，一般每噸干煤可生產(chǎn)300-350Nm3焦?fàn)t氣。

According to other data, 300-350nm3 coke oven gas can be produced per ton of dry coal.

焦?fàn)t氣熱值在4100-4600Kcal/m3

The calorific value of coke oven gas is 4100-4600kcal / m3

焦?fàn)t氣發(fā)電，1Nm3焦?fàn)t氣/1.1-1.2kwh.

Coke oven gas power generation, 1nm3 coke oven gas / 1.1-1.2kwh

Coking gas generator set

一般計(jì)算都是按330Nm3/t干煤，回爐煤氣大概45%，剩余煤氣大概55%。

The general calculation is based on 330nm3 / t dry coal, about 45% return gas and 55% residual gas.

焦?fàn)t煤氣按低發(fā)熱值算是17900kj/Nm3，焦化氣發(fā)電機(jī)組現(xiàn)在焦?fàn)t煤氣采用燃?xì)廨啓C(jī)發(fā)電利用率比較高，型式有好幾種，其中聯(lián)合循環(huán)發(fā)電或熱電聯(lián)產(chǎn)比較好，主要由燃?xì)廨啓C(jī)及發(fā)電機(jī)與余熱鍋爐、蒸汽輪機(jī)或供熱式蒸汽輪機(jī)（抽汽式或背壓式）共同組成系統(tǒng)，它將燃?xì)廨啓C(jī)排出的功后高溫乏煙氣通過余熱鍋爐回收轉(zhuǎn)換為蒸汽。

Coke oven gas is 17900kj / Nm3 according to the low heating value. The utilization rate of coke oven gas generator set is relatively high by using gas turbine for power generation. There are several types, among which the combined cycle power generation or cogeneration is better. It is mainly composed of gas turbine and generator, waste heat boiler, steam turbine or heating steam turbine (extraction or back pressure type), It converts the high temperature exhaust gas discharged from the gas turbine into steam through the waste heat boiler.

再將蒸汽注入蒸汽輪機(jī)發(fā)電，或?qū)⒉糠职l(fā)電作功后的乏汽用于供熱焦化氣發(fā)電機(jī)組。形式有燃?xì)廨啓C(jī)、蒸汽輪機(jī)同軸推動(dòng)一臺(tái)發(fā)電機(jī)的單軸聯(lián)合循環(huán)，也有燃?xì)廨啓C(jī)、蒸汽輪機(jī)各自推動(dòng)各自發(fā)電機(jī)的多軸聯(lián)合循環(huán)。

Then steam is injected into the steam turbine for power generation, or part of the exhausted steam after power generation is used for heating coking gas generator set. There are single shaft combined cycle driven by gas turbine and steam turbine, and multi shaft combined cycle driven by gas turbine and steam turbine respectively.

主要用于發(fā)電和熱電聯(lián)產(chǎn)，發(fā)電時(shí)的高 效率的聯(lián)合循環(huán)系統(tǒng)是ABB公司GT26-1，效率為58.5%。按58.5%效率計(jì)算一立方煤氣可以發(fā)2.9098度電。

It is mainly used for power generation and cogeneration. The high efficiency combined cycle system for power generation is ABB gt26-1, with an efficiency of 58.5%. According to 58.5% efficiency, a cubic meter of gas can generate 2.9098 kwh.
