在我国的工业锅炉中,凡采用燃煤方式的链条炉排锅炉,其除渣方式大多数都采用马丁式碎渣机。然而,该机在新投运后,最多能连续运行半年,在运行过程中,所出现的问题甚多。如:保险板更换频繁;停机后底部的防磨板上易沉积一层很坚硬的细灰渣和水垢的混合物;推渣器上的两个滚轮由于水和灰渣的作用而不滚动,把防磨板磨去两道深槽或被卡死;防磨板易磨损;水封液面不易控制,保持液面的溢流孔易被灰渣堵塞,至使灰水从上面的碎渣器和推渣器轴的轴瓦处溢流出,轴颈轴瓦易磨损;结构过于庞大,笨重。维护和检修的工作量大。
In our country’s industrial boilers, where the use of coal-fired chain grate boilers, the majority of its slag removal methods are used Martin-type slag shredder. However, the new machine put into operation, up to six consecutive years of operation, in the course of operation, there are many problems. Such as: frequent replacement of the insurance board; after the shutdown of the bottom of the wear plate is easy to deposit a layer of very hard mixture of fine ash and scale; slag roller on the two wheels due to the role of water and ash do not scroll, Anti-wear plate to two deep groove or stuck; Wear plate easy to wear; Seal liquid level is not easy to control, keep the surface overflow hole easily clogged with ash, so that gray water from the above slag device And push the shovel shaft bearing pad overflow, bearing bush easy to wear; structure is too large, bulky. Heavy maintenance and repair work.
