Product Detail

RTO relied on a range of materials for heat recovery, including ceramic blocks and saddles.

Alumina (Ceramic) Block as the classic ceramic structured packing of RTO ceramic heat exchange medias, also one kind of industrial porous ceramics with many passable parallel channels are ramified over its inside. It installed most in units bed designs of Regenerative Thermal oxidation to generate adequate thermal efficiency.

FAQ

1. What’s the delivery time ?

A: About 4 weeks for regular alumina blocks. (43 cells ,150*150*300mm) for 20 GP container.

2. How doesAlumina block work in RTOs Equipment ?

A : It let the straight-through flow prevents dust build-up and damage from aggressive chemicals ,also bring out maximum heat recovery and low pressure loss .

3. Why different shapes of cell ?

A : It differs from heat efficiency Conductivity through the Honeycomb ceramic passage .

4. What is the RTOs ?

A : Regenerative Thermal Oxidizer (RTO) is an industrial system that destroys volatile organic compounds (VOC’s) in process exhaust air before it pollutes the environment.

5.  Causes of ceramic block damage.

A : Impact , thermal shock damage , rapid steam vapor explosion,

6. How does monolith blocks work in RTOs ?

A: the Alumina blocks store the heat generated by the decomposition of VOCs, and uses the thermal energy stored in the alumina blocks to pre-heat and decompose the untreated VOCs, thereby achieving high thermal efficiency.
