At present, only about 35% of the fuel energy is converted into electric energy by the gas-fired generator set, about 30% is discharged with the exhaust gas, 25% is taken away by the cooling water of the gas-fired generator set, and other losses through the fuselage account for about 10%. The power lost by the exhaust gas and heat exchanger is more than the useful work.

在我國，目前占燃?xì)獍l(fā)電機(jī)組燃料近55%熱值的廢氣和冷 卻水余熱資源基本上被白白浪費(fèi)掉，燃?xì)獍l(fā)電機(jī)組余熱利用技術(shù)的就是來實(shí)現(xiàn)將原本白白浪費(fèi)掉的熱資源充分利用的系統(tǒng)。

In China, the waste heat resources of exhaust gas and cooling water, which account for nearly 55% of the calorific value of gas-fired generator fuel, are basically wasted. The purpose of waste heat utilization technology of gas-fired generator is to make full use of the wasted heat resources.

隨著生活質(zhì)量的提高，制冷和采暖越來越普及，能源消耗越來越大，同時燃?xì)獍l(fā)電機(jī)組余熱資源目前沒有得到綜合利用，消耗了大量能源。根據(jù)燃?xì)獍l(fā)電機(jī)組余熱利用現(xiàn)狀，我公司發(fā)揮技術(shù)優(yōu)勢，研制開發(fā)了一套燃?xì)鈾C(jī)組煙氣余熱利用配套熱管式余熱鍋爐及熱管換熱器，產(chǎn)生的過熱蒸汽和熱水用于余熱發(fā)電及企業(yè)內(nèi)部冷熱電聯(lián)供。

With the improvement of the quality of life, refrigeration and heating are more and more popular, and the energy consumption is increasing. At the same time, the waste heat resources of gas-fired generating units have not been comprehensively utilized, which consumes a lot of energy. According to the current situation of waste heat utilization of gas-fired generating units, our company has developed a set of heat pipe type waste heat boiler and heat pipe heat exchanger for waste heat utilization of gas-fired generating units. The superheated steam and hot water generated are used for waste heat power generation and internal CCHP.

在燃?xì)鈾C(jī)組發(fā)電的同時，以機(jī)組廢氣的熱量為能源，煙氣通過熱管余熱鍋爐及熱管換熱器，加熱介質(zhì)水，熱管余熱鍋爐產(chǎn)生的過熱蒸汽用于余熱發(fā)電，熱管換熱器產(chǎn)生的熱水通過溴化鋰?yán)渌畽C(jī)組制冷或制熱，系統(tǒng)

At the same time of generating electricity by gas-fired unit, the heat of unit exhaust gas is used as energy. The flue gas passes through heat pipe waste heat boiler and heat pipe heat exchanger to heat medium water. The superheated steam generated by heat pipe waste heat boiler is used for waste heat power generation. The hot water generated by heat pipe heat exchanger is cooled or heated by lithium bromide water chiller, and the system is stable

綜合利用燃?xì)獍l(fā)電機(jī)組熱能主要從三個方面著手：即電力供應(yīng)、采暖洗浴等供熱以及夏季空調(diào)制冷。在綜合利用的設(shè)計過程中應(yīng)充分考慮以下幾方面的因素：

The comprehensive utilization of heat energy of gas-fired generator sets mainly starts from three aspects: power supply, heating and bathing, and air conditioning and refrigeration in summer. In the design process of comprehensive utilization, the following factors should be fully considered:

a、利用應(yīng)避免對燃?xì)獍l(fā)電機(jī)組的性能產(chǎn)生大的影響，即不影響燃?xì)獍l(fā)電機(jī)組的正常運(yùn)行及功率輸出；

a. It should be avoided to have a great impact on the performance of gas-fired generating units, that is, it will not affect the normal operation and power output of gas-fired generating units;

b、排氣總管到余熱利用系統(tǒng)之間的距離應(yīng)盡可能短，同時應(yīng)充分考慮排氣管的隔熱保溫，減少從燃?xì)獍l(fā)電機(jī)組排氣出口至熱管余熱鍋爐的熱量損失；

b. The distance between the exhaust main pipe and the waste heat utilization system should be as short as possible, and the heat insulation of the exhaust pipe should be fully considered to reduce the heat loss from the exhaust outlet of the gas generator unit to the heat pipe waste heat boiler;

c、需要考慮燃?xì)獍l(fā)電機(jī)組負(fù)荷變化時給余熱發(fā)電及余熱制冷、制熱造成的影響，避免因負(fù)荷變化使制冷（或制熱）過量或能力不足；

c. It is necessary to consider the influence of the load change of gas-fired generating units on waste heat power generation, refrigeration and heating, so as to avoid excessive refrigeration (or heating) or insufficient capacity due to load change;

d、考慮到整個流程控制范圍大、項(xiàng)點(diǎn)多、操作難度大等因素，整個系統(tǒng)應(yīng)盡可能實(shí)行電氣自動化控制和監(jiān)測；

d. Considering the large control range, many items and difficult operation of the whole process, the whole system should implement electrical automation control and monitoring as far as possible;

e、整套系統(tǒng)應(yīng)充分考慮維護(hù)操作以及使用的安 全性。

e. The safety of maintenance operation and use shall be fully considered for the whole system.
