To reduce problems at the coal-fired thermal power plant caused by ash deposition, it is important to observe inside the boiler. We have developed an efficient new method to monitoring the phenomenon of ash deposition and clinker formation on the heat transfer surfaces in our pulverized coal-fired boiler in operation. Comparing ash area ratio, which indicated a degree of ash deposition obtained from the new method, with ash deposition level estimated by a human, it was shown to improve accuracy and efficiency of the observation. The proposed method can be applied to other coal-fired power plants worldwide to help improve operating conditions.
