Termo — Tech PRADO is a boiler installed in central heating installations. the production of which is made of 6mm thick boiler plate. This boiler has emission class 5 according to PN EN 303-5:2012 standard. For its proper combustion it is recommended to use pea-coak of 5-25mm granulation. In order to facilitate proper operation of the boiler, its operation is limited to firing up the automatic furnace and, if possible, regular ash removal. The automatic furnace is based on cyclical feeding of small portions of fuel directly to the retort grate and then the blower fan delivers the previously set amount of air to the furnace zone to fully optimize the combustion process. Thanks to this, we are able to achieve high efficiency of the combustion process and reduce the emission of harmful substances to the atmosphere.
The advantage of this type of boilers is:
