The air heater is an electric heating device that mainly heats the gas flow. The heating element of the air heater is a stainless steel electric heating tube. The inner cavity of the heater is equipped with multiple baffles (guide plates) to guide the gas flow and extend the retention time of the gas in the inner cavity, so that the gas is fully heated, the gas is heated evenly, and the heat exchange efficiency is improved. The heating element of the air heater, the stainless steel heating tube, is made by filling the seamless steel tube with electric heating wire, and the gap is filled with magnesium oxide powder with good thermal conductivity and insulation. After the tube is shrunk. When the current passes through the high-temperature resistance wire, the heat generated diffuses to the surface of the heating tube through the crystallized magnesium oxide powder, and then transfers to the heated air to achieve the purpose of heating.

Equipment Introduction

The air heater is an electric heating device that is installed in a cylindrical insulation container and a heating tube to heat the gas.

The air heater has the characteristics of fast heating speed, good insulation performance, and high heating temperature.

Air heaters are usually used to heat gases such as air and nitrogen, and can heat the gas to the required temperature in a very short time.

The specific size and heating time are customized according to customer needs

The pipe heater is an electric heating device that is installed in a cylindrical insulation container and a heating tube is used to heat gas and liquid.

The pipe heater has the characteristics of fast heating speed, good insulation performance, and high heating temperature.

Liquid pipe heaters are usually used to heat water, oil, and other liquids, and can heat the medium to the required temperature in a very short time.

The specific size and heating time are customized according to customer needs.

The pipe heater is an energy-saving device for preheating the material. It is installed before the material equipment to directly heat the material, so that it can circulate and heat at high temperature to achieve the purpose of saving energy. It is widely used in the preheating of fuel oils such as heavy oil, asphalt, and clear oil.

The pipe heater consists of two parts: the main body and the control system. The heating element uses stainless steel pipe as a protective sleeve, high-temperature resistance alloy wire, and crystallized magnesium oxide powder, which is formed by compression process. The control part adopts advanced digital circuits, integrated circuit triggers, high-reverse voltage thyristors, etc. to form an adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater.

There are two modes of pipe heaters: one is to use the flanged tubular electric heating element inside the pipe heater to be inserted upside down into the jacket of the reactor in the pipe heater to heat the heat transfer oil, and transfer the heat energy in the pipe heater to the chemical raw materials in the reactor inside the pipe heater. Another way is to directly insert the tubular electric heating element in the pipe heater into the reactor in the pipe heater or to evenly distribute the electric heating tubes around the wall of the pipe heater. This mode is called the internal heating type of the pipe heater. The internal heating type of the pipe heater heats up quickly and has high efficiency.
