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，目前占燃氣發(fā)電機組燃料近55%熱值的廢氣和冷 卻水余熱資源基本上被白白浪費掉，燃氣發(fā)電機組余熱利用技術(shù)的就是來(lái)實(shí)現將原本白白浪費掉的熱資源充分利用的系統。

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(zhù)生活質(zhì)量的提高，制冷和采暖越來(lái)越普及，能源消耗越來(lái)越大，同時(shí)燃氣發(fā)電機組余熱資源目前沒(méi)有得到綜合利用，消耗了大量能源。根據燃氣發(fā)電機組余熱利用現狀，我公司發(fā)揮技術(shù)優(yōu)勢，研制開(kāi)發(fā)了一套燃氣機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(guò)熱蒸汽和熱水用于余熱發(fā)電及企業(yè)內部冷熱電聯(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.

在燃氣機組發(fā)電的同時(shí)，以機組廢氣的熱量為能源，煙氣通過(guò)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(guò)熱蒸汽用于余熱發(fā)電，熱管換熱器產(chǎn)生的熱水通過(guò)溴化鋰冷水機組制冷或制熱，系統

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

綜合利用燃氣發(fā)電機組熱能主要從三個(gè)方面著(zhù)手：即電力供應、采暖洗浴等供熱以及夏季空調制冷。在綜合利用的設計過(guò)程中應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、利用應避免對燃氣發(fā)電機組的性能產(chǎn)生大的影響，即不影響燃氣發(fā)電機組的正常運行及功率輸出；

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之間的距離應盡可能短，同時(shí)應充分考慮排氣管的隔熱保溫，減少從燃氣發(fā)電機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、需要考慮燃氣發(fā)電機組負荷變化時(shí)給余熱發(fā)電及余熱制冷、制熱造成的影響，避免因負荷變化使制冷（或制熱）過(guò)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(gè)流程控制范圍大、項點(diǎn)多、操作難度大等因素，整個(gè)系統應盡可能實(shí)行電氣自動(dòng)化控制和監測；

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、整套系統應充分考慮維護操作以及使用的安 全性。

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