Kakšne so značilnosti grelnika zračnih kanalov

Hot blast stove is a very common kind in heating furnace. The use of electric heating elements can be designed and distributed according to the temperature requirements of users for heating medium. Its advantage is that it converts electric energy into heat energy and directly transmits the temperature to the interior of the heated object, so as to improve the work efficiency. On the heated medium, the speed of Zvišanje temperature na medij je zelo hitro, v celotnem ali delu določenega območja pa ostane le majhna količina preostalega plina in predmetov, ki lahko ogrevalno površino čistijo, ne vplivajo na nadaljnje delovanje in vsaj zmanjšajo onesnaževanje zraka .

In the R & D laboratories and scientific research institutes of enterprises, it is widely used in the production processes of transistors, appearance quenching of mechanical parts, melting of some alloys, and electric heaters are also widely used. Its development can better reflect its diversity, versatility, convenient installation and other advantages, and can provide better services for the production and life of all sectors of society.

The electric heater of air duct is mainly used for air heating in the air duct{{0}} Its specifications are divided into three forms: low temperature, medium temperature and high temperature. The common thing is to support the electric heating pipe with steel plate to reduce the vibration of the electric heating pipe. The over temperature control device is installed in the terminal box. In addition, in terms of control, a connecting device is set between the fan and the heater. After the electric heater is started, a differential pressure device shall be added at the front and rear of the heater to ensure that there will be no fan failure. The gas pressure heated by the channel heater is generally 0, and the medium temperature is below 260 high temperature type 500.
