Abstract

A multi-pipe external-heating coal decomposition equipment, comprising a airtight kiln body; a channel for impelling and decomposing coal is formed in the kiln body, which has a coal inlet, a coal outlet and a collecting pipe for coal decomposition gas; a heat transfer chamber is formed between the channel and inner wall of the kiln body, which is connected with a high temperature gas heating facility and comprises a heated gas outlet. Because the channel for impelling and decomposing coal is set in a kiln body with high temperature, so a vast of heat gas in high temperature kiln body surrounds the channel and its heat conducts and radiates to the pulverized coal in the channel. Thus, the pulverized coal can fully absorb the heat to be heated for decomposing to the gas, coal tar and coal with high heat-value in the channel.
