The device what points need to be taken into account when heat resistance?

Is very strict to the requirement of unit heat resistance, not only need to install the smooth and firm, all kinds of parameters must be measured, but also in the efficient maintenance care is simple. In order to meet these stringent requirements, have to give special attention to the device when the device is part of the thermal resistor and the depth of the insert, can be summarized as the following two points.

one, choose reasonable location of measuring points, try to avoid in the device's corner or valves, elbow and pipe device heat resistance. Second, want to know if with maintenance casing, thermal resistor will be on the heat transfer and heat loss, should deepen the degree of thermal resistance and thermocouple insertion and make measurement error reduced. 1, in general, should put the thermal resistance measurement (vertical or inclined to the measurement of the pipe at the center of the place, such as pipe diameter is 200 mm, so heat resistance is 100 mm to be inserted. 2, if there is a delay in the flue temperature, even if the flue is 4 meters in diameter, thermal resistance insert 1 meter is ok. 3, in the measurement of element insert deeper than 1 meter, the estimate is the vertical device. Even if we have to install thermal resistance is very skilled, but still must be conducted in accordance with the prescribed steps to device. ( Figure/http://www. wuxiyibiao。 com )
