Steam heater steam heat exchanger
The steam heaters commonly used in drying equipment are blade type and spiral fin type. At present, the radiator row heater has been standardized. The necessary heating area can be calculated according to the required temperature, heat consumption and air inflow speed, and then the standard heater can be selected.
The steam heaters commonly used in drying equipment include vane type and spiral fin type. There are two kinds of heater materials: steel and copper. Steel pipe and steel sheet should be preferred in the selection.
The steam heater used in the drying device is usually composed of several groups in series.
At present, the radiator row heater has been standardized. The necessary heating area can be calculated according to the required temperature, heat consumption and air inflow speed, and then the standard heater can be selected.
（1） SRZ type radiator (spiral fin radiator)
SRZ type spiral fin heater is used for air heating with steam pressure of 0.03-0.58mpa. Its characteristics are as follows:
(1) Due to the mechanical winding, the heat dissipation fin is firm and the heat transfer performance is good and stable. The resistance of air passing through is small.
(2) There are 38 kinds of dimensions.
(3) Light weight.
(4) Beautiful appearance, convenient installation and durability.
