TECHNICAL FIGURES
Technology specification(technical figures)
Efficiency (heat, electrical, total) – main, well known
Availability, reliability
Level of automation
Efficiency drop working at partial load
Efficiency drop working at specific conditions
Minimum achievable capacity
Wood chips boiler minimum achievable capacity is about 25 – 35% of nominal capacity. For electrical boilers starting from almost 0.
Minimum achievable capacity
Technology specification(technical figures)
Wood chips boiler. Nominal capacity 55 MW.Minimum about 15 MW
Minimum achievable capacity
Solution 1
Technology specification(technical figures)
Wood chips boiler. Nominal capacity 100 MW.Minimum about 25 MW
Minimum achievable capacity
Solution 2
Technology specification(technical figures)
Solution 1 in comparison with Solution 2Lose Win
Minimum achievable capacity
Does additional production for Solution 2 justifies construction of 100 MW boiler instead of 55 MW?In this case it seems not
Technology specification(technical figures)
If no hot tap water production exist
(district heating network does not operate outside district heating
season).
Does additional production for Solution 2 justifies construction of 100 MW boiler instead of 55 MW?In this case it seems so

FINDING OF ECONOMIC AND TECHNICAL DATA IS NOT ALWAYS EASY WORK
MAINLY IT IS NECESSARY TO CHECK AND COMPARE DIFFERENT SOURCES.
DATA ACCURANCE STRONGLY AFFECT TO PLANNING RESULTS.
