Electric Mineral Insulated Heaters For Ash Bucket Power Plant

Product Specification

Plate Electric Heater for Ash Bucket for Power Plant is an electric heating equipment composing of electric heating body, digital display temperature controller, power supply and temperature control cabinet. It is suitable for long term automatic temperature control of dust hopper of dust collector, slag storehouse and dewatering storehouse as well as heating and heat preservation for air conveying chute and buried scraper. The method is to use the outer wall heating of the ash hopper to supplement the temperature difference of the outer wall of the ash hopper to prevent wet dust condensation, dust accumulation and hinder flow.

Ash bucket plate electric heater is an ideal heating equipment in the dust removal system in power plant industry, and can also be extended to petroleum, chemical, cement, metallurgy, machinery and other industries.

Product features of Ash bucket plate electric heater:

Ash bucket plate electric heater adopts advanced heating method, high quality heating materials and accurate temperature control, with the advantages of energy saving, simple structure, high mechanical strength, easy installation, good insulation performance, uniform heating, high thermal efficiency, long service life and so on. Temperature control cabinet can control automatic and constant temperature, with overload, over current protection function. The digital display temperature controller is equipped with working state indicator, which can indicate the working state of each group of electric heaters, and can independently set and control the temperature of each group of electric heaters correspondingly. The control cabinet has good interchangeability between each group of units.

In recent years, the ash bucket plate electric heater has been adopted by many power plants.

Ash bucket plate electric heater application:

It is suitable for automatic temperature control of dust hopper of dust collector, slag storehouse and dewatering storehouse, air conveying chute and buried scraper for heat preservation and heating.

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.
