掺烧褐煤磨煤机干燥出力问题分析及对策

在烟煤锅炉上掺烧褐煤时,磨煤机的干燥出力下降已经成为制约掺烧褐煤的一个瓶颈,出现的一个突出问题就是由于褐煤的水分含量很高而造成原有磨煤机干燥出力严重不足,致使磨煤机制粉能力严重下降,本文全面分析粉系统于燥剂的温度水平偏低原因并提出应对措施.

Design and implementation of the optical fiber control and transmission module in multi-channel broadband digital receiver

An optical fiber control and transmission module is designed and realized based on Virtex-7 field programmable gata array （FPGA）, which can be applied in multi-channel broadband digital receivers. The module consists of sampling data transfer submodule and multi-channel synchronous sampling control submodule. The sampling data transmission in 4× fiber link channel is realized with the self-defined transfer protocol. The measured maximum data rate is 4.97 Gbyte/s. By connecting coherent clocks to the transmitter and receiver endpoints and using the self-defined transfer protocol, multi-channel sampling control signals transferred in optical fibers can be received synchronously by each analog-to-digital converter （ADC） with high accuracy and strong anti-interference ability. The module designed in this paper has certain reference value in increasing the transmission bandwidth and the synchronous sampling accuracy of multi-channel broadband digital receivers.
