Convection heating in Electric Ovens for Powder Coating

Convection heating is carried out by heating the air surrounding the article to be the stove. This is generally done by having a heating chamber where the air is heated and the heated air is circulated inside the oven chambers by means of fans.

Normal sources used to heat the air are electricity, gas, steam, or oil. Convection ovens are suitable for both batch continuous operations depending on the workload.

A limitation of the convection-type oven is that it will usually be required to be started from 20 minutes to half an hour before stoving operations can begin.

This is because the air inside the oven will have to be heated to the required temperature and this takes time. Normally the temperature in a convection oven is thermostatically controlled so that the heat and therefore the fuel consumption is regulated depending upon the amount of work entering the oven.

As the object is heated by the circulation of air, any shape and size of the object can be dried by convection heating. This method is generally used for drying of large castings, machined components, and objects having a nonuniform weight distribution.

Radiation Heating

This is attained by heating the source so that the source starts emitting infrared radiation and this radiation heats up the paint film. The infrared emission can be directed towards the object to be heated by means of suitably shaped reflectors if necessary.

The absorption of the radiation takes place at the surface of the charge and infrared heating is thus essentially a surface heating process. Since infrared radiation is emitted in straight lines from the source or reflector, plain surfaces are most readily treated. In infrared paint stoving the temperature attained by the paint film depends upon the intensity of radiation on the painted surfaces, the time of exposure, and the mass of the article.

The color of the paint also plays a part in the speed with which the surface is heated. Black paints tend to absorb more heat, whereas glossy white paint requires a longer time of exposure. For infra-red heating, infra-red gas burners working of LPG gas, infra-red bulbs or infra-red electrical heaters can be used.

Conditioning Functions of Electric Ovens for Powder Coating

• The heating of the oven with an electric heating system is achieved by recirculating oven air through Incoloy sheathed tubular heaters. The heaters are mounted in the conditioning plenum and are isolated from the workspace to prevent direct heat radiation.
• Air circulation is generated by either one or two propeller-type fans, which are driven by externally mounted motors. The Model MPC35.21 employs one fan, while the Model MPC45.96 employs two. Airflow is in a compound horizontal pattern through the oven workspace.
• A two-inch diameter exhaust port is provided at the top of the oven to vent moisture or undesirable vapors given off by your heating process. An exhaust kit for connection to an exhaust stack is optional.

Temperature Controller

The temperature controller of an electric powder coating oven is a device that regulates the temperature of the oven chamber. It is a critical component of the powder coating process, as the curing temperature must be precisely controlled to ensure the desired finish.

• Proportional-integral-derivative (PID) controllers: PID controllers are the most common type of temperature controller used in electric powder coating ovens. They continuously monitor the oven temperature and make adjustments to the heating elements to maintain the desired temperature.
• Thyristor power controllers: Thyristor power controllers are another type of temperature controller that can be used in electric powder coating ovens. They use a series of solid-state switches to control the amount of power that is supplied to the heating elements. This allows for very precise temperature control.

The temperature controller is typically located on the front of the oven and has a digital display that shows the current temperature. The controller also has a number of buttons and knobs that can be used to set the desired temperature, curing time, and other parameters.

Here are some of the key features of a temperature controller for an electric powder coating oven:

• Accuracy: The temperature controller must be able to accurately measure and control the oven temperature. This is important to ensure that the powder coating cures properly.
• Repeatability: The temperature controller must be able to repeat the same curing temperature consistently. This is important to ensure that the powder coating finish is uniform.
• Ease of use: The temperature controller should be easy to use and program. This is important to ensure that the oven can be operated efficiently.

Safety features: The temperature controller should have safety features such as over-temperature protection and emergency stop.

When choosing a temperature controller for an electric powder coating oven, it is important to consider the type of powder coating you will be using, the size of the oven, and your desired finish. You should also consult with a powder coating specialist to get their recommendations.

Here are some additional tips for using a temperature controller for an electric powder coating oven:

Overtemperature Protection

Overtemperature protection is a safety feature that automatically shuts down an electric powder coating oven if the temperature exceeds a certain threshold. This is important to prevent the oven from overheating and causing a fire.

There are two main types of overtemperature protection systems used in electric powder coating ovens:

• Bimetallic thermostats: Bimetallic thermostats are the most common type of overtemperature protection system used in electric powder coating ovens. They consist of two strips of metal with different coefficients of expansion. As the temperature rises, the strips expand at different rates, causing the thermostat to trip and shut down the oven.
• Resistance temperature detectors (RTDs): RTDs are another type of overtemperature protection system that can be used in electric powder coating ovens. They measure the temperature of the oven chamber using a resistance element. As the temperature rises, the resistance of the element increases. If the resistance exceeds a certain threshold, the RTD will trip and shut down the oven.

Overtemperature protection systems are typically located in the oven chamber and are wired to the oven’s control system. If the temperature exceeds the set threshold, the overtemperature protection system will trip and shut down the oven.

Advantages of overtemperature protection:

• Prevents the oven from overheating and causing a fire
• Protects the oven and its components from damage

A high-volume compound horizontal airflow system is employed with the electric heating system to provide maximum temperature uniformity. The heating and generation of airflow occur in the conditioning plenum,
which is normally located on the right side wall of the oven. Airflow is generated by propeller-type fans at approximately 2400 CFM. The fans are driven with extended shafts by motors mounted in the control cabinet.

Heating is achieved with Incoloy sheathed type tubular heaters, which are suspended in the conditioning plenum. This location prevents direct radiation to the product. To condition the workspace, Model MPC35.21 ovens utilize one heater bank with one circulation fan, and the Model MPC45.96 – 2D ovens utilize two heater banks with two circulation fans.

When additional heated modules are added to the MPC45.96 series, the plenums will be identical in construction and controlled by the same conditioning circuitry

Airflow Description

Electric ovens using centrifugal-type blower wheels for airflow generation employ a horizontal front-to-back type airflow system. The burner manifold is designed with a vertically mounted flame tube along with perforations on the back side of the manifold. Processed air is drawn into the burner manifold and conditioning plenum, and is heated as it mixes with hot air emitted from the flame tube.

Fresh ambient air is also drawn into the plenum where it mixes with the heated air. Conditioned air is discharged into the workspace through perforations near the front of the plenum housing. The air flows back through the workspace in a horizontal manner to condition the product and then returns to the plenum for reconditioning.

A portion of the processed air is exhausted through a port in the chamber ceiling by the exhaust blower. An air intake port with a manual slide damper is installed in the ceiling of each module to allow fresh ambient air to replenish the exhausted air. Slide dampers are mechanically locked to a predetermined minimum opening.

Electric Heat Control System

Incoloy sheathed tubular heating elements are used to heat the oven. The unheated heater ends protrude through the wall of the oven and into the control cabinet where they are electrically terminated.

The heat control circuitry is enabled through the High Limit output of the Yokogawa UT150L Limit Controller, along with either one or two heat enable contractors (CON1 / CON2). In the Model MPC35.21, one contactor is used in both single and three-phase power-supplied units. In the Model MPC45.96 – 2D, one contactor is used with a three-phase power supply, and two contractors are used with a single-phase power supply.

Two contactors are required with a single-phase supply because the heaters are split into two separate circuits. The heaters are controlled by the time proportioned Heat Output of the Yokogawa UT150 Temperature Controller.

This output energizes a two-pole solid-state relay, which provides power to the heaters. The relay employs two SCRs in each pole in a back-to-back configuration. Zero cross-voltage switchings is employed to give precise temperature control with minimal noise generation.

A critical stage in the powder coating process is the curing phase, where the applied powder undergoes a transformation from a dry state to a durable, smooth finish.
