|
No. |
Indicators |
Value |
|
1 |
Boiler type |
Stationary, with natural circulation |
|
2 |
Boiler steam-generating capacity |
Maximum capacity for this cell, but no less than 30 MTPH |
|
3 |
Steam temperature, °С |
370±10°С |
|
4 |
Steam pressure at outlet, MPa |
2,4 |
|
5 |
Air temperature, °С |
-30 +40 (provide for recirculation line for air heating upstream air preheater by air heated by boiler air heater) |
|
6 |
Fuel: |
|
|
6.1 |
Tail gas*:
|
As per Appendix No. 1 |
|
6.2 |
Natural gas*: а) calorific value Qнр , kcal/ Nm3 б) density r, kg/ Nm3 в) temperature, °С г) pressure, MPa д) flow limit for nominal conditions, m3/h |
а) 8158-8560 б) 0,7095-0,7473 в) 2,6-21 г) 0,036-0,038 д) no more than 100
a) 8158-8560 b) 0,7095-0,7473 c) 2,6-21 d) 0,036-0,038 |
|
7 |
Waste gas flow rate |
Up to 45000 m3/h |
|
8 |
Natural gas flow rate |
For rated tail gas flow no more than 50 m3/h (per boiler). In the absence of tail gas, ensure boiler rated steaming capacity using natural gas |
|

|
11 |
Rupture discs |
Yes |
|
12 |
Design of boiler and its elements |
The design of a boiler and its elements must ensure complete emptying both when mounted and at storage site. |
