•
Emergency cooling coil is utilized for alarm cooling of circulating water
in the boiler’s heat exchanger in case that the water temperature has
reached high levels. This coil has connecting thread of size G½”;
•
The flue exit duct (the external diameter is described in table 2.2) is
positioned in the back upper of the boiler and extracts the flue gases out of
the convective section of the boiler;
•
The heat exchanger is thermally insulated with mineral wool, which
allows lower heat loses to the surrounding atmosphere;
•
The doors of the fuel hopper and the combustion chamber are fabricated
from cast iron, which allow high thermal resistance and air tightness of
the boiler;
•
The outer covers of the boiler are manufactured from steel plates and are
finally color painted;
The next figures show the dimensions and the design of the wood gasification
hot water boiler of series “Pyrotherm”.
