The common straw stalk gasifier uses spurts the spout is becomes with the line pipe welding, because the gasifier fixed property was mad when the reaction temperature amounts to about 1200 degrees, the line pipe namely starts about 600 degrees to oxidize, a temperature higher oxidation falls off is quicker, will use about 3 months to oxidize normally, one year must replace multiple, the post-sale service is very difficult to do, will be many gasifier Production enterprise inextricability difficult problem, we will invest more than 40 ten thousand Yuan introduction special-purpose compression casting equipment. Uses the thermostable alloy material compression casting to become, the thermostable 1600 degrees, guarantee the long-term use
