3. Description 3.1. Boiler construction The boiler body (Fig. No.1) consists of sections assembled by means of forced-on insertions and is secured by anchor bolts. Boiler has a three-draught construction and the sections create the combustion space and the convection part, inside then the boiler water space. The tightness of boiler gas combustion space is guaranteed by boiler cement applied to sections seating faces and to circumference of individual section joints.
