Direct fire hated brewhouse
———Is my burner capacity big enough for my brewhouse?
Here are three popular options to heat the brewhouse of microbrewery-electric, steam and direct fire. A friend from Australia just asked me if our recommended burner suitable to their 2000L brewhouse well. The following information have a example to explain this good question.
I will still take the 2000L brwhouse as the example.
(for 2000L brewhouse we actually recommend the steam heating).
Let’s say that the burner will heat the 2000L kettle and 4000L hot liquor tank.
We usually use the Baltur burner, a famous brand of Italy-http://www.baltur.cn/cn/en/
We recommend BTG20, it's thermal power is 60kw-205kw (we can control the thermal power via controlling the inlet of the gas quantity )
We consulted the staff who is the agency in China for the Baltur burner, and know the loss of the thermal power is 10% for the burner itself, so we can get that the maximum actual thermal power from the burner is184kw (205KWX0.9)
When the burner is heating under the brewery brewhouse, here are another two thermal losses: the thermal loss at the vent that is taken away by the air, and the thermal loss while the heating goes through the stainless steel plate where a thermal difference always exists from the flame to the SS plate bottom of brewhouse, and from SS plate bottom to the wort. The thermal loss from this two places is total around 10% again.
So the final maximum thermal power when it arrives wort is 205KWX0.9X0.9=166KW.
When we heat the 4000L water from 20C to 74C:
(74C-20C)X4200J/KG.CX4000L=time X 166kw X 3.6x10^6
We can get: 1.52hrs 81% efficiency
Heating speed: Around 0.6C/minute
When we heat up 2000L wort in kettle from 65C to 100C
Similar we can get: 0.5hr 81% efficiency
Heating speed: Around 1.16C/minute (usually 1C-1.5C is good for heating the wort).
BTG20 is the minimum capacity to heat the 2000l brewhouse.
Another size of BTG28 has a slightly larger capacity to heat faster in case any necessary, since BTG28 has the thermal power from 80kw-280kw
So BTG28 is also a nice choice for 2000L brewhouse.
