As can be seen from Table I, general power is knowable, so, the power of T3a positions heating cylinder can be calculated, so not
Influence equipment works.
When any heating cylinder is broken, all the heat that the heating cylinder being broken is disappeared can be supplemented by other heating cylinders, for example
T3a positions heating cylinder is broken, and is shown in Table two：
| T1 | T2a | T3a | T4 | T5 | General power |
| 6.75kw | 6.75kw | 0kw | 6.75kw | 6.75kw | 27kw |
| 5.5kw | 5.5kw | 0kw | 5.5kw | 5.5kw | 22kw |
| 4.25kw | 4.25kw | 0kw | 4.25kw | 4.25kw | 17kw |
Because required heat is clear and definite, as can be seen from Table II, although do not heated at T3a, but heated by by other
The power of cylinder is improved, and also can be the heat for compensating heating cylinder loss at T3a.In addition, from table two compared with table one, although production
Speed and machine are identical, but, when being worked in the way of table two, general power is big compared with the working method general power of table one, so, heating
The quantity of cylinder needs reasonable layout, not necessarily smaller, and power is just smaller.
T1, T2a, T3a, T4 and T5 are respectively the first heating cylinder, the second heating cylinder, the 3rd heating in above-mentioned table one and table two
Cylinder, the 4th heating cylinder and the 5th heating cylinder.
