彩乐乐彩票燃气发电的发展还存在哪些制约因素?

燃气发电在我国已经试运营多年,但是因为这样或那样的原因,现在的发展程度还远不理想,阻碍我们燃气发电的发展到底还存在哪些制约因素?不要心急,我们接着慢慢看下去。
Gas-fired power generation has been in trial operation for many years in China, but for one reason or another, the development level is far from ideal. What are the constraints hindering the development of gas-fired power generation? Don't worry, let's go on slowly.
一.燃气发电中心技术未完整控制,限制燃气发电产业开展目前,国内制造企业与国外企业协作中在关键技术方面存在壁垒,对燃气发电中心技术还不完整控制,主要表如今以下几个方面:
1. The technology of gas power generation center is not under complete control, which limits the development of gas power generation industry. At present, there are barriers in key technology between domestic manufacturing enterprises and foreign enterprises, and the technology of gas power generation center is not under complete control. These are mainly manifested in the following aspects:
1、燃机设计制造中熄灭器、透平叶片等热部件完整依托进口,开展存在瓶颈。国内制造企业固然可以制造、组装燃气发电机组,但在整机设计、热部件资料制造以及冷却和隔热涂层等关键技术方面尚未完成本质性打破,燃机熄灭器、透平叶片等热部件仍完整依托进口。
1. In the design and manufacture of gas turbines, extinguishers, turbine blades and other thermal components rely entirely on imports, and there are bottlenecks in their development. Although domestic manufacturing enterprises can manufacture and assemble gas-fired generating units, they have not yet completed essential breakthrough in key technologies such as machine design, data manufacturing of thermal components, cooling and thermal insulation coatings. Thermal components such as gas turbine extinguishers and turbine blades are still completely dependent on imports.
2、整机检修维护依赖原厂商,维修费用昂贵。受设备设计制造中心技术不控制的限制,国内对整机检修维护中心技术控制不深、不透,机组检修维护、改造晋级、部件改换等都依赖原厂商,主要部件发作毛病需返厂检修,检修维护费用昂贵。
2. The maintenance of the whole machine depends on the original manufacturer, and the maintenance cost is expensive. Limited by the technical uncontrollability of the equipment design and manufacturing center, the technical control of the whole machine maintenance center in China is not deep and thorough. The maintenance, upgrading and replacement of the units are all dependent on the original manufacturer.

3、机组运转中熄灭参数不能自主调整,运转平安存在隐患。熄灭调整为原厂商的中心技术,必需由原厂商停止。燃机发电企业没有控制整机熄灭调整的规范和参数,运转人员不能经过熄灭自动调整确保机组在熄灭脉动小和在排放佳点运转,不利于有效控制平安情况和展开异常诊断、剖析。
3. The extinguishing parameters of the unit can not be adjusted independently, and there are hidden dangers in the safe operation of the unit. Extinguishing is the central technology of the original manufacturer, which must be stopped by the original manufacturer. Gas turbine power generation enterprises do not control the norms and parameters of the whole machine extinction adjustment. Operators can not automatically adjust the extinction to ensure that the unit operates at the minimum extinction pulsation and the optimum emission point, which is not conducive to effectively control the safety situation and carry out abnormal diagnosis and analysis.
二.燃气发电设备设计制造质量存在问题,影响机组运转牢靠性近年来,国内燃气发电机组存在设计制造质量问题,压气机、熄灭器及热通道部件、发电机、燃气系统等毛病多发,尤以F 级机组较为突出。
2. There are problems in the design and manufacture quality of gas-fired power generation equipment, which affect the reliability of unit operation. In recent years, there are problems in the design and manufacture of domestic gas-fired power generation units. Compressor, extinguisher and heat channel components, generators, gas systems and other faults occur frequently, especially in class F units.
三.机组性能不能完整顺应运转请求和环境条件,影响设备寿命我国燃气发电机组大局部引进国外技术,不能完整顺应国内运转方式和运转环境,设备维修周期和运用寿命相应缩短。
3. Unit performance can not fully comply with operation requirements and environmental conditions, affecting equipment life. Most of the gas-fired generating units in China import foreign technology, can not fully comply with domestic operation mode and operation environment, and equipment maintenance cycle and operation life are shortened accordingly.
四.燃气发电无序开展问题较为突出,自然气供给与发电不谐和有关项目审批单位、自然气供给企业、电力调度机构、燃气发电企业在燃气机组装机容量与自然气供给量、发电用气量与发电量、供气方式与电网调峰等方面没有有效衔接,发电、供气存在不谐和现象。
4. Unorderly development of gas-fired power generation is a prominent problem. There is no effective connection between the installed capacity of gas generating units and the supply of natural gas, power dispatching agencies and gas-fired power generating enterprises, and between the installed capacity of gas generating units and the supply of natural gas, the consumption of generating gas and the output of generating electricity, the mode of supplying gas and peak shaving of power grid.
