我们综述了适用于燃煤系统测量的非接触诊断技术。就地测量需要在光学不透明的二相或三相系统中使用具有高透入深度的方法。可用的非接触法对测量原子组分是有效的。声学技术和微波技术已经得到应用,并提供了有关固相质量流量、温度、速度和物质浓度的数据。尚未获得为实现实时过程控制或燃烧室放大所需的燃烧室模拟数据,故需发展一些像X线、微波或长波红外线层析照相术等新的诊断手段。
We review non-contact diagnostic techniques for coal-fired system measurement. In-situ measurements require the use of methods with a high penetration depth in optically opaque two-phase or three-phase systems. The available non-contact method is effective for measuring atomic components. Acoustic and microwave technologies have been applied and provide data on the mass flow, temperature, velocity and concentration of solids. No simulations of the combustion chamber needed to achieve real-time process control or chamber amplification have yet to be developed, and new diagnostic tools such as X-ray, microwave, or longwave infrared tomography need to be developed.
