Currently, the waste heat resources of exhaust gas and cooling water, which account for nearly 55% of the calorific value of fuel in gas generator units, are basically wasted in vain. The purpose of the waste heat utilization technology for gas generator units is to achieve a system that fully utilizes the originally wasted heat resources.

隨著(zhù)人民生活質(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 people's quality of life, refrigeration and heating are becoming more and more popular, and energy consumption is increasing. At the same time, the waste heat resources of gas turbine generators are not being comprehensively utilized, consuming a large amount of energy. According to the current situation of waste heat utilization of gas generating units, our company has developed a set of heat pipe type waste heat boilers and heat pipe heat exchangers for waste heat utilization of flue gas from gas generating units, utilizing its technical advantages. The superheated steam and hot water generated are used for waste heat power generation and internal cooling, heating, and power cogeneration in the enterprise.

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，系統原理如下圖所示：

While generating electricity from a gas turbine, the heat of the unit's exhaust gas is used as the energy source. The flue gas flows through a heat pipe waste heat boiler and heat exchanger, heating the medium water. The superheated steam generated by the heat pipe waste heat boiler is used for waste heat power generation. The hot water generated by the heat pipe heat exchanger is cooled or heated by a lithium bromide water chiller. The system principle is shown in the following figure:

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 thermal energy from gas turbine generators mainly involves three aspects: power supply, heating, bathing, and other heating, as well as summer air conditioning and refrigeration. The following factors should be fully considered in the design process of comprehensive utilization:

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. Utilization should avoid having a significant impact on the performance of the gas generator unit, that is, not affecting the normal operation and power output of the gas generator unit;

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；

The distance between the exhaust manifold and the waste heat utilization system should be as short as possible, and full consideration should be given to the thermal insulation of the exhaust pipe 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 impact on waste heat power generation, waste heat cooling, and heating caused by load changes of gas turbine generator units, to avoid excessive cooling (or heating) or insufficient capacity due to load changes;

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, multiple items, and difficult operation of the entire process, the entire system should implement electrical automation control and monitoring as much 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 of the entire system should be fully considered.
