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的就是來實現將原本白白浪費掉的熱資源充分利用的系統(tǒng)。
In China, the waste gas and cooling water waste heat resources, which currently account for nearly 55% of the calorific value of gas generator unit fuel, are basically wasted. The waste heat utilization technology of gas generator units is to achieve a system that fully utilizes the originally wasted heat resources.
隨著人民生活質量的提高，制冷和采暖越來越普及，能源消耗越來越大，同時燃氣發(fā)電機組余熱資源目前沒有得到綜合利用，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)揮技術優(yōu)勢，研制開發(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，產生的過熱蒸汽和熱水用于余熱發(fā)電及企業(yè)內部冷熱電聯供。
With the improvement of people's quality of life, refrigeration and heating are becoming increasingly popular, and energy consumption is increasing. At the same time, the waste heat resources of gas generator units have not been comprehensively utilized, consuming a large amount of energy. Based on the current situation of waste heat utilization in gas power generation units, our company has utilized its technological advantages to develop a set of gas unit flue gas waste heat utilization supporting heat pipe waste heat boiler and heat pipe heat exchanger. The generated superheated steam and hot water are used for waste heat power generation and internal cooling, heating, and power supply within the enterprise.
在燃氣機組發(fā)電的同時，以機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，加熱介質水，熱管余熱鍋爐產生的過熱蒸汽用于余熱發(fā)電，熱管換熱器產生的熱水通過溴化鋰冷水機組制冷或制熱，系統(tǒng)原理如下圖所示：
At the same time as generating electricity from the gas turbine, the heat from the exhaust gas of the unit is used as the energy source. The flue gas passes through the 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, and the hot water generated by the heat pipe heat exchanger is cooled or heated by the lithium bromide 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方面著手：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程中應充分考慮以下幾方面的因素：
The comprehensive utilization of thermal energy from gas generator units mainly starts from three aspects: power supply, heating and bathing, and summer air conditioning and refrigeration. 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. The 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(tǒng)之間的距離應盡可能短，同時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 full consideration should be given to the insulation and insulation of the exhaust pipe to reduce 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 generator units, in order to avoid excessive cooling (or heating) or insufficient capacity due to load changes;
d、考慮到整個流程控制范圍大、項點多、操作難度大等因素，整個系統(tǒng)應盡可能實行電氣自動化控制和監(jiān)測；
d. Considering the large control range, multiple items, and high operational difficulty of the entire process, the entire system should implement electrical automation control and monitoring as much as possible;
e、整套系統(tǒng)應充分考慮維護操作以及使用的安全性。
e. The entire system should fully consider the safety of maintenance operations and use.
