Overview of air heater:
The gas electric heater is a heat exchange device that converts into heat energy. It has the advantages of convenient energy supply, compact structure, automatic temperature control, and has the advantages of easy installation and maintenance, and less pollution.
Structure composition of gas electric heater:
The gas electric heater is composed of a tubular container and electric heating elements, and is equipped with a temperature control cabinet (set). The control part adopts advanced digital circuits, integrated circuit triggers, high back pressure thyristors, etc. to form an adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater. The heating element adopts a straight tube type instead of a U-shaped structure, and it is easy to install and disassemble by using a special plate hand. The temperature control adopts thyristor adjustment and PID digital display. Within the temperature control range, the required temperature can be set arbitrarily, and the temperature is automatically maintained at ±5°C. It also has over-limit sound and light alarm and multiple protection functions, which can be controlled locally or remotely. There are other needs can be customized production processing.
Working principle of gas electric heater:
The power supply gas electric heater is a new type of heating equipment for the ash removal system of coal-fired power plants. It is suitable for heating by gasification wind in the air conveying chute of the power station, gasification wind in the ash bucket of the electric precipitator, and gasification wind heating in the ash storage. The equipment consists of two parts, the gas electric heater body and the control system. The heating element adopts 1Cr18Ni9Ti stainless steel tube as protective sleeve, 0Cr27Al7MO2 high temperature resistance alloy wire and crystalline magnesium oxide powder, which are formed by compression process. The electric heating tube has good thermal conductivity and excellent insulation. There is a deflector inside the heater for uniform heating. The gas electric heater control cabinet and the gasification fan are equipped with interlocking control functions and local control and remote control interfaces. When the equipment is restarted after a sudden shutdown, the control cabinet can automatically and smoothly adjust and play a buffer role.
Application areas of gas electric heaters:
The gas electric heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 850°C. It has been widely used in many scientific research and production laboratories such as aerospace, weapons industry, chemical industry and universities. It is especially suitable for the test of automatic temperature control and large flow high temperature combined system and accessories. The gas electric heater can be used in a wide range: it can heat any gas, and the generated hot air is dry and moisture-free, non-chemically corrosive, non-polluting, non-conductive, non-combustible, non-explosive, safe and reliable, and the heated space heats up quickly ( Controllable).
