Dust hopper heating technology - dust - Filtration and Separation Industry
Automatic thermostat heater type dust hopper is fighting for the power industry need to dust heating needs of the development of new thermal electric heating device. Can guarantee long-term specified in the automatic temperature control, to prevent dust and moisture condensation, dust, impeding smooth flow. The method of heating the outer wall of gray bucket, ash bucket wall temperature added to achieve the purpose of dehumidification flowing.
Traditional electric wire plate heater since they do not have the automatic control function of heating temperature, while relying solely on temperature controller to control the heating temperature, when the temperature controller fails, it is prone to overheating overheating. When the temperature drop necessary to compensate for the temperature compensation has a slower pace. The typical drawback is that life is short, energy consumption, maintenance costs high.
Dust hopper type thermostat heater with excellent electrical characteristics with a new generation of ceramic materials as fever, when the voltage on the ceramic heater with external temperature, the heat in the cold ceramic body resistance is low, by the current large, rapid warming electric heater; when the temperature reached the set temperature switch, ceramic heater resistivity increases rapidly, so current is reduced to a constant value, the power consumption of all of this time spread to the walls of dust hopper to achieve automatic thermostat and save energy.
Technical Features 1, long service life
As a result of automatic temperature characteristics of ceramic materials and anti-aging properties of heat insulation excellent temperature materials, coupled with advanced structural design, the normal life of up to 5 to 10 years.
2, safe and reliable Ceramic material in the heat when the heat was no fire, not oxygen, its production formula has been fixed temperature points can be maintained for life, and its failure modes will not be reflected in loss of control over temperature, or fuse, safe and reliable use .
3, save energy Ceramic heater material itself heat conversion rate, but also because the characteristics of automatic constant temperature, the heat load changes, can quickly increase or decrease power. That when the heat load increases, the heat loss can be compensated quickly, not to increase due to heat load dehumidification dust removal effect; particularly in the heat load is reduced, the power only to maintain the hopper wall temperature, energy saving very obvious.
4, uniform heating Each hopper is equipped with several groups of automatic temperature-type electric heater unit, uniform in the hopper wall, the total power of 8 ~ 20KW / fighting, take power way for three-phase four-wire system ensures a balanced three-phase power.
5, voltage adaptable Because of this material
- voltage of ceramic heater can be in a certain range (25%) of the power supply voltage fluctuations can still maintain a constant temperature condition, it is common electric wire material does not have the features.
6, warming quickly Special ceramic heater current - time characteristics, determine its fast warming is heating wire material is far from uncontested.
7, easy to install
Dust hopper type thermostat with electric heater temperature thermal adhesive tape and protective wall installed in the hopper, outlet simple and dust-proof, waterproof, UV aging, and easy maintenance.
