1.2 COMPONENT OF THE BOILER
1.2.1 INTRODUCTION
Main parts of the boiler DENAPAK:
Pressurized combustion chamber and the convection part.
The boiler consists of upper and lower drum to which are connected the plurality of tubes
forming a right, left, back and front wall, which together form the casing of the boiler.
Another part of the boiler tube walls are composed of:
- Combustion chamber in which heat is transferred mainly by radiation
- Convection part, in which heat is transferred mainly by radiation
Gas-tight welded and cold perimeter walls with insulation and sheeting.
The burner is on the front wall of the combustion chamber.
The combustion chamber is provided with peepholes. Individual parts of the boiler are made available to hatch.

1.1.2 DESCRIPTION BOILERS
The boiler consists of:
a) 1 steam drum consisting of two dished a cylindrical section 1190 mm, length 9500 mm, wall thickness 70 mm, wall thickness of the bottom 40 mm.
The drum is provided with a manhole. Inside there is an internals and steam separator.
b) one water-drum consisting of two arched and cylindrical section 740 mm, length 9500 mm, wall thickness 40 mm, wall thickness of the bottom 30 mm.
The drum is provided with a manhole inside the drum feedwater heaters from Tr ø 51 / 3.6.
c) steam drum is provided specific level indication chamber outer diameter 219 mm, to which are attached 2 straight with level and 3 level monitor connected to the M + R boiler.
d) one convection tube bundle evaporator of Tr ø 51 / 3.6.
e) 1 convection tube bundle evaporator (input-protection) from the Tr ø 51 / 3.6.
f) 1 rear wall of the drum Tr ø 51 / 3.6.
g) 1 diaphragm walls of Tr ø 57/5 D-shaped, which forms the combustion chamber.
h) one left side wall of the combustion chamber of Tr ø 51 / 4.5
i) one front and one rear wall of Tr ø 57/5. Both walls at the bottom of the mouth of the chambers Tr ø168 / 20.
These chambers are connected with a water drum Tr ø 57/5.
j) 1 left outer side wall of the boiler Tr ø 57/5
k) 8 downpipes ø 114.3 / 4.5. Pipes are 4 pieces located outside the flue gas stream at both ends of the cylindrical part of the drum.
l) 20 outlet steam pipes ø 57/5. These pipes to a collecting chamber steam Tr ø 219/16 welded and into the steam drum rolling. The bottom of the steam chamber are ø 219/38.
m) superheater 1 consists of coils Tr 33.7 / 4, an inlet chamber Tr ø 219/16, the bottom ø 219/33, the outlet chamber Tr 219 / 12.5, the bottom ø 219/33.
n) superheater consists of two coils Tr 33.7 / 5, an inlet chamber Tr 219 / 12.5, the bottom ø 219/33, the outlet chamber Tr ø 219/16, the bottom ø 219/33.
