PTC vs MCH Ceramic Heating: How to Choose the Right Industrial Igniter
In industrial high-temperature heating and biomass combustion ignition systems, ceramic igniters are gradually replacing traditional nickel-chromium resistance wire heating solutions. Ceramic heating technology outperforms traditional heating solutions in heating rate, energy efficiency and working lifespan. PTC heaters and MCH metal ceramic heaters represent the two mainstream heating technologies on the market. They feature distinct material structures, temperature control mechanisms, maximum temperature ratings and applicable fields. Such core differences greatly influence equipment ignition performance, system stability and long-term maintenance expenses. I. Working Principle of PTC Heaters PTC (Positive Temperature Coefficient) heating elements use barium titanate (BaTiO3) semiconductor ceramic as the core material, characterized by a significant increase in resistance with rising temperature. Its working process is as follows: ...
