Regenerators cleaning

During the regenerative glass furnaces operation occurrs the sulphate condensation on the checkers. 

The blocked checkers inhibit the regular air streaming and so that the air preheating does not reach the right temperature and the fuel consumption is higher and the furnace economy is worse. BHW supplies the regenerators cleaning by the way of the sediments melting. This is provided by heating up burners with a special changeable adapter. Burners are placed under checkers on the regenerator bottom.
