    380V Mineral Insulated Heaters

    Mineral Insulated Electric Heater for Residue and Heavy Oil Preheating is designed based on magnesium oxide mineral insulated heating cable as heating element for the preheating of the resudue and heavy oil which are widely used for the industrial kilns


    Mineral Insulated Electric Cable Heater for Marine Vessel Fuel Oil Preheating is an electric heater based on mineral insulated heating cable to be used for the fuel oil preheating on a marine vessel. The Heater breaks the viscosity of fuel oil, while increase inflammable point of heavy fuel oil, and also increases oil temperature up to the degree which helps purification process.


    Second, technical properties

    1. The heat transfer performance of the heating element of this product is good, and the temperature difference between the heating core and the metal sheath is small. At the same time, according to the process requirements, the surface heat load density of the heating element of the MI heating cable can be accurately designed. Under the premise of ensuring the total heating power, the heated medium will not coke. It solves the shortcomings of the traditional tubular electric heaters for long-term carbon deposition, blasting, core breaking and short life. The heating element can with a copper or a stainless steel sheath according to the application temperature and location.

    2. The outer shell of the electric heater is welded by seamless steel pipe and flange. The overall structure is tight and firm and the pressure sealing performance is good for safe use. The normal working pressure is 0.6MPa~6.4MPa.

    3. The device connection and electrical connection meet the explosion-proof requirements with an explosion-proof grade d IIBT1—T6.

    4. Two sets of temperature sensors are installed in electric heater to detect the temperature of the oil and the surface temperature of the heating element. At the same time, the flow locking device can be optionally selected according to the user's needs. When the medium does not flow, the electric heater automatically stops heating.

    5. No daily maintenance is required and it is easy to be installed and convenient to be maintained.

    6. The product is practical and adaptable. Various non-standard types of electric heaters can be designed according to the different uses and special requirements put forward by users.

    Note: When designing an electric heater for using outdoors, the explosion-proof junction box should have a rainproof shed to prevent rainwater from impregnating the gap of the explosion-proof surface through the wet insulation material.


    Third, structure and working principle

    1. Structure

    The electric heater structure consists of nine parts. (See Figure 1)

    1 Inlet pipe 2 Diversion Chamber 3 Heating Chamber 4 Temperature Measuring Resistor 5 Over Temperature Protector 6 Junction Box 7 Oil Outlet Pipe 8 Mixed Flow Chamber 9 Sewage Outlet


    Figure 1: Schematic diagram of liquid electric mineral insulated heater


    2. Working Principle

    The cold medium enters the diversion chamber through the oil inlet, so that the medium flows into the mixing chamber along the periphery of the heating element, and the mixed medium flows out from the oil outlet at a uniform temperature. The mixing chamber is equipped with a temperature measuring sensor, and the temperature signal is collected and transmitted to the electronic control system. The temperature control instrument controls the primary circuit to realize automatic control of the oil temperature. When the oil products or electric heating element of the heater is overheated, the protection device automatically cuts off the power supply and the control cabinet emits an audible and visual alarm signal.
