Nozzle dedicated for reduction furnace

2010-08-11View Original

Thread Content

The quality of the nozzle design in reduction furnaces directly affects the likelihood of the formation of those \"corn kernel\"-like patterns on the surface of polycrystalline silicon rods. Many manufacturers of reduction furnaces now have their own patented nozzles – such as GT, 3P, and those produced by SenSong in China – but what is the actual performance of these nozzles in practice? It is not yet possible to determine whether it is just marketing hype by the manufacturer or indeed has practical value in use; if anyone has relevant information, please share it with us.

I want to know that too; my company’s models don’t have special nozzles

It is usually sold together with the furnace; it’s not available for purchase separately. Moreover, in theory, the flow field simulation for each furnace is different, so there are certainly differences in the air inlet nozzles, and the performance when using them together cannot be guaranteed

Some patents are fraudulent, while others are genuine; manufacturers certainly won’t let you easily know which ones are legitimate

Regarding nozzles, most of them are lies, used as a tactic to promote their reduction furnaces

In actual production, in many cases it is necessary to create nozzles that suit one’s own manufacturing processes. . . . . . . . .

What kind of nozzles are suitable for one’s own manufacturing process? ?

I completely agree. In the past two years, many patents have emerged in the polysilicon industry, but most of them are worthless; in some cases, the applicants themselves don’t even understand the so-called patents they’ve filed – it’s pure deception!

The furnace is a product of comprehensive performance; relying solely on nozzles or some single patented technology is ineffective. Just like with cars, the engine needs to be good, but there are many factors that determine the quality of a car.

Special nozzles require numerous tests to yield satisfactory results. Initially, the angle of the nozzle is adjusted repeatedly to find the optimal gas flow pattern for each reduction furnace, taking into account the effects of the temperature distribution as well.

Regarding nozzles, most of them are a form of deception, used as a means to promote their reduction furnaces. But it can’t be said absolutely that this is the case in every instance. :lol
