Industrial electric high pressure pipeline inline air heater

Short Description:

The pipeline inline air heater is an industrial electric heating device specifically designed to heat gases flowing inside pipelines. Its inlet and outlet are connected to the pipeline, which converts electrical energy into thermal energy to heat the temperature of the gas in the pipeline.

Product Introduction

The pipeline inline air heater is a device that uses electrical energy to heat air flowing through pipes or pipelines. It is directly installed in the airflow. When air flows through a blower in a pipeline/duct, current passes through a resistance heating element installed inside the pipeline. At this time, the air flowing through the element absorbs heat through convection, and the outlet air temperature is controlled and monitored by a thermocouple temperature measurement and controller (based on PID, SSR).

Working principle

Pipeline electric heater is a device that consumes electrical energy to convert it into thermal energy for heating materials that need to be. During operation, the low-temperature fluid medium enters its inlet under pressure, flows through the specific heat exchange channels inside the electric heating vessel, and follows path designed based on fluid thermodynamics principles, carrying away the high-temperature heat energy generated by the electric heating elements, thus increasing the temperature of the heated medium The outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically regulates the output power of the heater according to the temperature sensor signal at the outlet, maintaining a uniform temperature of the medium at the outlet; when the heating element overheats, the independent over protection device of the heating element immediately cuts off the heating power supply, preventing the heating material from overheating, causing coke, deterioration, and carbonization, and severe cases, causing the heating element to burn out, effectively extending the service life of the electric heater.

Product details display

The air circulation pipeline heater is composed of two parts: body and control system.Electric heating element generates heat: The electric heating element in the heater is the core part of generating heat. When an electric current passes through these elements, they generate a lot of heat.

Forced convection heating: When nitrogen or other medium passes through the heater, the blower is used to force convection, so that the medium flows and passes through the heating element. In this way, the medium, as a heat carrier, can effectively absorb heat and transfer it to the system that needs to be heated.

Temperature control: The heater is equipped with a control system including temperature sensor and PID controller. These components work together to automatically adjust the output power of the heater according to the outlet temperature, ensuring that the medium temperature is stable at the set value.

Overheating protection: In order to prevent overheating damage to the heating element, the heater is also equipped with overheating protection devices. As soon as overheating is detected, the device immediately cuts off the power supply, protecting the heating element and the system.

Product feature

1.Efficient and energy-saving: Electric energy is directly converted into thermal energy with high conversion efficiency (usually>95%). Good insulation design further reduces heat loss.

2.Accurate temperature control: PID control can achieve temperature control accuracy of ± 1 ° C , meeting strict process requirements.

3.Quick response: Electric heating starts quickly and the temperature rise and fall rate is relatively fast.

4.Clean and environmentally friendly: No combustion process, no exhaust gas, smoke or flames are generated, and the working environment is clean.

5.Easy to automate: Easy to integrate into PLC/DCS systems for remote monitoring and automated control.

6.Relatively easy to install: usually connected by flange and connected to the pipeline directly.

7.Flexible design: The power, size, and structure (such as explosion-proof type) can be customized according to gas flow rate, temperature rise requirements, pipeline size, pressure, gas composition, etc.

Product application

Pipeline inline air heaters are widely used in many application scenarios, like:

Chemical and Petrochemical: Heating process gases (such as nitrogen, hydrogen, argon, carbon dioxide, cracking gas, reaction gas), preventing gas condensation, preheating before gas desulfurization and denitrification, etc.

Oil and natural gas: heating natural gas (antifreeze, depressurization and anti icing), associated gas, flare gas, pipeline heating after liquefied petroleum gas (LPG) gasification, natural gas dehydration/pre metering heating, etc.

Electricity: Heating boiler air (primary air, secondary air), flue gas reheating of desulfurization system, etc.

Environmental protection: Preheating of exhaust gas in VOC waste gas treatment (catalytic combustion, RTO/RCO).

Laboratory: Precise control of experimental gas temperature.
