In using Sodium silicate equipment users to use coal for heating. Use of coal heating, will encounter a little trouble, that is the bar will be high temperature coal fusing. As soon as the fuse will need to have the corresponding alternative bar to use, but the bar is a frequently used very few goods, so in many places it is difficult to buy almost, this is not to say that as bar how technology content, but because of who I am bar to use less and less, so there are very few stores specializing in this product. Why the bar will be fusing. Bar in theory by fusing the chance is very small. As long as the normal use, the rate of fuse is not large, the main reason for the fuse is Sodium silicate furnace equipment pit coal cinder is overmuch, let leakage of coal direct contact met bar, which can form a local space for high temperature, high temperature in the space, completely reached the fusing bar temperature, therefore can appear such circumstance. How we want to avoid this, avoid measures is also very simple, actually that's ashes, often keep the ashes in the hearth in less of a situation, the leakage of crushed coal will relatively far from the bar, since such temperature cannot reach the temperature of the fusing bar, nature also can get a long time.
