Overview

By using constant-temperature heating, it raises the internal temperature of the insulation chamber, preventing condensation, moisture absorption, ash accumulation, and creepage caused by flue gas infiltration. This avoids high-voltage insulation degradation, electric field flashover, and frequent tripping. It effectively ensures stable operation of the porcelain insulation and high-voltage electric field under conditions of high humidity, low temperature, and large temperature fluctuations. It is an essential temperature control component for stable operation of electrostatic precipitators in winter and humid weather, preventing leakage faults.

Features

It features precise constant-temperature heating and automatic temperature control capabilities, continuously raising the internal temperature of the insulation chamber and maintaining it above the flue gas dew point temperature. This fundamentally prevents condensation and moisture absorption problems in the porcelain insulators, stabilizing the equipment's insulation performance.

Employing high-quality heating elements and a sealed housing, it provides uniform heating, high heat conversion rate, and rapid temperature rise, eliminating localized overheating. It boasts excellent temperature resistance, moisture resistance, and dustproof performance, making it suitable for long-term constant-temperature operation within the sealed chambers of dust removal equipment.

Features an intelligent temperature control system supporting automatic start/stop, constant temperature locking, and over-temperature protection. It offers high temperature control accuracy and automatically adjusts heating power based on ambient temperature and humidity, eliminating ineffective energy consumption and achieving significant energy savings.

It operates stably, without open flame, and has a high safety factor. It is vibration-resistant and resistant to airflow interference, making it suitable for harsh industrial environments characterized by humidity, dust, and large temperature differences. It is not prone to burnout or malfunction during long-term operation.

Its compact and highly adaptable structure saves internal space. Uniform heating coverage ensures all-around dryness and cleanliness of insulating components, effectively improving the overall operational stability and sustained ultra-low emissions of the electrostatic precipitator.

Suitable Applications

Widely compatible with various dry and wet electrostatic precipitator insulation chambers, porcelain insulator chambers, and high-voltage hanging boxes for dedicated heating and moisture protection. Mainly used in electrostatic precipitators (ESPs) operating in high-humidity flue gas, low-temperature environments, and large diurnal temperature variations, such as thermal power generation, heat supply, metallurgical sintering, cement kiln tail, chemical tail gas, waste incineration, and biomass combustion. Suitable for industrial sites with year-round humidity and low temperatures prone to condensation in winter.

Maintenance Design

The equipment comes standard with a complete heating core, temperature control probe, intelligent temperature controller, sealed protective shell, and fixing accessories. The accessories are comprehensive and highly versatile. The overall dustproof and moisture-proof sealed design is suitable for enclosed dust removal equipment. Supports customization of multiple power levels, voltages, and standard/explosion-proof specifications. Matching models can be made according to the size of the insulation chamber, ambient humidity, and low-temperature operating conditions, compatible with new and old dry and wet ESPs for installation, replacement, and upgrades.

Note

The heater is designed to prevent condensation, maintain insulation, and stabilize the electric field. It is an essential accessory for ESPs operating in low-temperature and humid conditions. Long-term shutdown can easily lead to probe failure and heating attenuation. Regular checks of temperature control accuracy and heating status are necessary to prevent insulation moisture from causing electric field tripping and shutdown.
