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

在我國，目前占燃氣發動機燃料近55%熱值的廢氣和冷卻水余熱資源基本上被白白浪費掉，發動機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。

In China, the waste heat resources of exhaust gas and cooling water, which currently account for nearly 55% of the calorific value of gas engine fuel, are basically wasted. The purpose of engine waste heat utilization technology is to realize the full use of the waste 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，同時發動機余熱資源目前沒有得到綜合利用，燃油、燃氣及電熱鍋爐和空調在廣泛使用，消耗了大量能源。根據發動機余熱利用現狀，我公司發揮信息和技術優勢，研制開發了國內套燃氣機余熱利用空調，用于我公司辦公大樓和會議室的熱電聯供。

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, engine waste heat resources have not been comprehensively utilized. Oil, gas, electric boilers and central air conditioners are widely used, consuming a lot of energy. According to the current situation of engine waste heat utilization, our company has developed the first set of gas engine waste heat utilization central air conditioner in China, which is used for cogeneration of heat and power in our office building and conference room.

在燃氣機組發電的同時，以機組廢氣的熱量為能源，煙氣通過特制的熱交換系統加熱介質水，使水溫達到規定溫度，通過溴化鋰冷水機組制冷或制熱，通過風機盤管空調器給房間制冷或供熱。系統原理如下圖所示：

At the same time of generating electricity from the gas unit, the heat of the unit exhaust gas is used as the energy source. The flue gas heats the medium water through the special heat exchange system to make the water temperature reach the specified temperature. The room is cooled or heated by the lithium bromide water chiller, and the room is cooled or heated by the fan coil air conditioner. The system principle is shown in the following figure:

應用范圍

Scope of application

1、辦公大樓、賓館、商場的熱電聯供制冷、供熱系統。

1. Cogeneration refrigeration and heating systems for office buildings, hotels and shopping malls.

2、利用燃氣發電站余熱資源為聯合站加熱原油。

2. Use the waste heat resources of gas power station to heat crude oil for the combined station.

概括的來說，凡是需要熱能并且已有機組或燃氣資源豐富的地方都可以推廣應用。

In general, it can be popularized and applied in places where heat energy is needed and there are existing units or rich gas resources.

發動機的廢氣余熱利用在我國還是一個新興的科技領域，是發展的必然趨勢，我們還要不斷學習國外在這方面的先進技術，提高水平，多與廣大用戶交流和學習，提高余熱利用效率，擴大應用范圍，以使其擴展到更寬的領域，更好的為用戶服務，使用戶達到收益化。

The utilization of waste heat from engine exhaust is still a new scientific and technological field in China, which is an inevitable trend of development. We should continue to learn from foreign advanced technologies in this field, improve our level, communicate and learn more with the majority of users, improve the efficiency of waste heat utilization, expand the scope of application, so as to expand it to a wider field, better serve users, and maximize the benefits of users.
