Abstract
Most of the new boilers recently installed in Finland are multifuel boilers using woodwastes and peat as the main fuel. Although burning of woodwastes and peat is economically most attractive, noticeable difficulties are encountered in the combustion control due to such fuel characteristics as varying physical properties, moisture value etc. In this project a control strategy was developed for the Tampella double-grate boiler. Special attention was paid to the grate burning properties and the function of the mechanical grate. The control system consists of the optimization of the Tampella multifuel boiler (K10) and the steam levelling control system of the power plant. Because of the rapid load fluctuations caused by boarding machine web breaks or fluctuations in digester house steam demand, a steam network levelling system was installed in the power plant. The main object of the project was to minimize oil burning in the K10-boiler and the whole power plant and the optimization of grate burning. The practical results of the mechanical grate function control and air distribution optimization are very encouraging. During normal operation boiler pressure and excess oxygen are very stable compared with other grate boilers. The response time of boiler load changes is also very fast
