Honeycomb Ceramic Regenerator (Monolithic Type) vs Combined Plate Honeycomb Ceramic Regenerator

The two main technical approaches to recovering high-temperature flue gas waste heat and improving combustion efficiency are honeycomb ceramic regenerator (monolithic type), combined plate honeycomb ceramic regenerator.This article aims to objectively compare their technical characteristics to provide a professional basis for selection.

1. Comparison of Core Features

Combined Plate Honeycomb Ceramic Regenerator

This product is assembled from corrugated ceramic plates, forming intersecting flow channels, and is specifically designed to handle complex and harsh industrial conditions.

Structure: Modular assembly with staggered flow channels.

Clog Resistance: Wide and unobstructed flow channels effectively prevent dust blockage.

Stability: Distributes thermal stress, provides strong thermal shock resistance, and ensures reliable structure.

Heat exchange: Flow channel design enhances disturbance response, resulting in high heat exchange efficiency.

Pressure drop: Non-linear flow channels lead to relatively high system operating resistance.

Honeycomb Ceramic Regenerator (Monolithic Type)

This product undergoes a one-time extrusion molding and sintering process to form a monolithic component with numerous parallel straight channels, specifically designed for efficient heat transfer and low flow resistance.

Structure: One-piece molding with parallel, regular, and densely distributed channels.

Heat Transfer: Large specific surface area, rapid thermal response, and high theoretical heat transfer efficiency.

Pressure Drop: Low resistance in the straight channels helps reduce system energy consumption.

Clog Resistance: The small channels are prone to clogging under high dust conditions, affecting performance.

Stability: There is a risk of overall cracking under extreme temperature shocks.

2.Main Applications and Selection Guide

Operating conditions suitable for combined plate honeycomb ceramic regenerator:

High-dust, high-impurity flue gas environments (e.g., steel rolling furnaces, waste incinerators, glass melting furnaces);

Frequent start-stop operations with large temperature fluctuations;

Production lines with high requirements for continuous production and limited maintenance windows.

Operating conditions suitable for honeycomb ceramic regenerator (monolithic type):

Clean fuel, low-dust flue gas conditions (e.g., aluminum processing furnaces and forging furnaces using natural gas);

Scenarios where induced draft fan capacity is limited during system upgrades and pressure drop is a concern.

3.Summary

Combined plate and integral honeycomb heat storage are designed for different industrial needs. Selection should comprehensively consider flue gas conditions, operating procedures, and cost-effectiveness.
