Ceramic honeycomb blocks are the key componets of RTO

Compared with the square hole structure of ceramic blocks , hexagonal hole structure has six 120 degree angles, smaller curvature of corners, smaller back pressure, 14% lower pressure drop, larger heat exchange area, higher heat exchange rate, flow efficiency can be increased by 15%. More walls, more uniform structure, better to heat exchange and resistance to silicon, iron and other impurities erosion and clogging. Hexagonal hole structure represents the densest filling structure per unit area. Relative to square holes, 15% more holes can be added with the same inscribed circle radius. Compared with the square hole, 72% more heat exchange contact points significantly improve the conduction efficiency. Other hole shapes of ceramic blocks are also available in our company: quare, rectangle, rotundity, triangle,  and others your requested

How can we extend the usage of RTO blocks  to avoid  to be damaged?  You can do like followings: 1.Try to put the blocks in order when you install the block; 2. Keep expansion gap every 1 centimeter per 1meter evenly distributed when place the blocks; 3. The speed of temperature rise and fall should not be too fast, otherwise it will easily cause cracking in the regenerator product. Within 300°C, the heating rate is ≦ 30°C/h, which mainly excludes adsorbed water; when the temperature is 300-600°C, the rate of temperature rise and fall is 60°C/h, and when the temperature is higher than 600°C, the rate of temperature rise is ≦ 120°C/h; when the temperature is lowered, the temperature is lowered. Speed ≦ 60°C/h; 4.In the working conditions, if there are too many nano-dusts (silicon, organic titanium, etc.), the pores of the regenerator product will be blocked, causing uneven temperature and pressure, and finally leading to product crackin; ...

RTO’s stands for Regenerative thermaloxidizers ( are the most common oxidizer in today’s market. RTO’s are capable of extremely high thermal efficiencies up to 97%. When considering a replacement oxidizer, RTO’s can cut the customer’s gas cost considerably making the switch an easy decision.   Due to their high thermal efficiency, RTO can often go into “self-sustain” mode, in which the burner shuts off completely, using zero gas. Longevity is also another big advantage for the RTO, because the heat exchanger and combustion zone are internally lined with refractory insulation. There are no internal steel components which are exposed to reaction chamber temperature.Regenerative thermal oxidizers can achieve high thermal efficiencies due to the ceramic media. Each process is evaluated by our engineers to determine the correct media for the application. We utilize either structured (honeycomb) media or random packed media in the RTO design, depending on the application.

T he waste produced by ceramic honeycomb has not only makes trouble for companies to deal with, but also for the government which will destroy the environment. Earlier ， ceramic waste was considered as a “burden” by the factories due to the absence of related recycling technology. It was solved like a “garbage” by a simple landfill ， or was used to fill a trench, a roadbed, etc. Even more directly fell to the roadside, farmland, rivers and other places. Because ceramic waste cannot be degraded, the waste contains chemical substances that seriously pollute the water, air and soil environment. In recent years, many ceramic companies have strengthened research projects such as the recycling of non-renewable resources, and have made gratifying achievements in reducing the generation of pollutants from the source. A variety of waste bricks have been crushed into large quantities for use as raw materials, and sludge slags of various types of ceramic bricks have also begun to be applie...
