Installation schemes 

 

A  plant  scheme  must  be  fit  for  the  technical 
boiler features: so it’s possible to utilize in the 

better  way  boiler’s  efficiency  and  to  keep  the 
plant in good conditions for a long time 

In  Figure  8  is  shown  an  installation  without  a 
mixing element, in Figure 9 is shown a installa-

tion with a mixing element.
