The production is stopped as soon as the fabric temperature reaches the condensing temperature of steam.
In an embodiment, the condenser (410) arranged to cool the torrefaction gases to a condensing temperature, wherein the condensing temperature is between 10 ° C and 40 ° C.
In one example, a sensor measures the temperature difference between sub-cooled liquid and saturated condensing temperature and provides information to the controller.
By means of a liquid temperature adjustment unit (31), the temperature-regulating fluid is adjusted so as to be at a temperature higher than the condensing temperature of the reactive component.
As a result, the temperature at a compressor outlet and a condensing temperature are raised to supply hot water at a higher temperature for indoor heating or supplying hot water.
As a result, the condensation pressure and the condensation temperature can be reduced.
The surface is at a temperature below the condensation temperature of the vapor.
A heat exchange temperature sensor (33) detects the condensation temperature of the cooling medium.
The configuration of the duct is such that the exhaust gas reaches the condensation temperature in the vicinity of an upper section (5) of the condensation economizer (4).
It is then cooled rapidly to a temperature less than 30 °C above the original dew point.
The gaseous contaminants includes odorous portions and condensable portions which have a condensation temperature.
Surprisingly, it has emerged that the difference in temperature between the boiling temperature and the condensation temperature, created in the mixture, is not as high as indicated in the literature.
The heat exchanger receives from the oven at least a first air flow at a first temperature, wherein the first temperature is above the condensation temperature, and including gaseous contaminants.
