The copper\u2019s design and its main geometrical sizes are given below in figure 1.<\/strong>
Copper is the steel cylinder surrounded by other steel cylinders of bigger diameter with a heater. The heat carrier heats up between cylinders.<\/strong><\/p>\n\n\n\n

The fuel loading door 10, clean sweep door group 11, Draught limiter connection sleeve pipe 17, the thermometer 19 are located in the boiler\u2019s front part. There are stack gases stub tube 9, coolant delivery stub tube 15, return water stub tube 16 in the back part of a boiler. The air damper 21 and the secondary air regulator 20 are located on the boiler\u2019s upper cover 22. The air heating camera 5 is mounted for fuel burning quality and heat transmission improvement in the upper part of the combustion chamber. In order to avoid boiler bottom heating a row of a fire-clay brick (fettling) 12 is located in the lower part of a firepot 1.<\/p>\n\n\n\n

For optimum heat removal achievement between air heating camera and combustion chamber walls of a boiler there is a gap across the perimeter whereby the smoke, enveloping the air heating chamber, comes into the carry fumes hole.<\/p>\n\n\n\n

The telescopic pipe of air supply 6 descends into combustion chamber, at the end of which fastens an air distributor burner device 7. On the right side of a copper, opposite to a door, there is a cable 13 for air delivery heaving with a ring 14 and the fixing hook.<\/p>\n\n\n\n

The air distributor\u2019s purpose is to give air into the burning zone evenly. The air distributor leans down the extent of fuel combustion under the force of its weight.<\/p>\n\n\n\n
