The Calorimeter Temperature Sensor

The enhancement of the C-3500 flame depth calorimeter was generally for the measurement of combustion chamber warmth fluxes in energy generating facilities. The calorimeter temperature sensor permits the direct and instantaneous electric power analysis of combustion chamber gasses for most effective stoichiometric fuel/air blend. In addition, the calorimeter is commonly made use of in verifying heat resource intensities at diverse cracking tower stations together the complete oil refinery method, which assures system repeatability. A further critical software is utilized to the flame screening of supplies and elements below Federal Aviation Restrictions. Other purposes contain electrical power technology, hotbox flame control, jet exhaust output, organic gasoline energy written content, reactor output, furnace intensity and a number of ASTM flame test evaluations.

The flame depth temperature sensor is a 1.00 – 2.00 inch diameter, rod that is put in immediate contact with the heated gasses. The sign created is directly proportional to the regional heat flux a radial traverse of the resource yields a evaluate of the overall power output. The sensor yields D.C. millivolt alerts that can be measured with traditional millivolt meters or recorders.

How the Calorimeter Works

The C-3500-3600 Flame Calorimeter is to be inserted through a port immediately into the combustion gasoline stream. The HT-fifty High Temperature Warmth Flux Transducer has been welded and heat sunk to a place 50mm from the suggestion of the C-3500 Probe(C-3600 has sensor at tip of probe).

The spot of this sensor is on the same aspect as the water discharge port and has been temporarily marked for your ease. This area need to be famous and located so that the combustion gasses impinge straight on it. The finest detected fluxes will take place when the sensor site is at 900 or at a stagnation issue to the flame entrance.

The calorimeter incorporates an interior h2o feeding tube within the hollow cylindrical probe. Interesting drinking water enters by way of the internal tube and flows out as a result of the annular hole involving the inner tube and interior wall of the outer probe tube. A handle process may differ the fee of move of h2o to keep the inside temperature of the probe wall at a constant worth. H2o coolant should be supplied to the probes rear inlet at a stream price of ten – twenty Liters/Moment. Boiling of the cooling water need to by no means be authorized, for quite high thermal flux rates, the water/coolant move price will have to be improved right up until the exit h2o temp is tepid. The average heat flux is calculated by multiplying the C-3500-3600 Calibration Frequent by the calculated DC micro-voltage.
