Air duct electric heater Structural composition of

Air duct Electric heater It is a heat exchange equipment which is converted into heat energy. It has the advantages of convenient energy supply, compact structure, automatic temperature control, easy installation and maintenance, and less pollution.

 Heater air duct manufacturer

Structural composition:

Gas electric heater The utility model is composed of a tubular container and an electric heating element, and a temperature control cabinet (table). Advanced temperature control and high voltage control circuit are adopted to ensure the normal operation of the system. The U-shaped tube and the special heating element can be replaced by the straight tube. The temperature control adopts silicon controlled rectifier adjustment and PID digital display. Within the temperature control range, the required temperature can be set arbitrarily, and the constant temperature can be automatically maintained at ± 5 ℃. It also has over limit sound and light alarm and multiple protection functions, which can be controlled locally or remotely. Other needs can be customized production processing.

working principle:

Power supply gas electric heater is a new type of heating equipment for ash handling system of coal-fired power plant. It is suitable for heating the air conveying chute gasification air of power station, the gasification air of ash hopper of electrostatic precipitator and the gasification wind of ash silo. The equipment is composed of gas electric heater body and control system. The heating element is made of 1Cr18Ni9Ti stainless steel tube as protective sleeve, 0cr27al7mo2 high temperature resistance alloy wire and crystal magnesia powder, which are formed by compression process. The electric heating tube has good thermal conductivity and insulation, and a guide plate is set inside the heater to heat evenly. Gas Electric heater control cabinet It has interlock control function, local control and remote control interface with gasification fan. When the equipment is restarted after sudden shutdown, the control cabinet can automatically adjust smoothly and play a buffer role.

Application fields:

Gas electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850 ℃. It has been widely used in many scientific research and production laboratories such as aerospace, weapon industry, chemical industry and colleges and universities. It is especially suitable for automatic temperature control and large flow high temperature combined system and accessories test. The gas electric heater can be used in a wide range: it can heat any gas, and the hot air produced is dry and free of moisture, chemical corrosivity, non conductivity, non combustion, non explosion, and the temperature of the heated space is fast (controllable).
