NOVELTY - A straw type coal comprises corn straw and plant straw comprising peanut shell, sear cauline leaf, paddy straw, wheat straw, or their mixture; where the weight ratio of corn straw and plant straw is 45-70:20-26 if the raw material components of the molded coal is corn straw and peanut shell or corn straw and sear cauline leaf; and the weight ratio of corn straw and plant straw is 45-70:65-70 if the raw material components of the molded coal is corn straw and paddy straw.    USE - The straw type coal is useful for industrial and commercial applications.    ADVANTAGE - The straw type coal has heat value that can reach 3200-4500 kilocalorie, and ash content of 5-9%, while the sulfur content is less than 0.05 % and the combustion rate reaches more than 95%. Moreover, the discharge concentration of the combustion smoke gas totally reaches the requirement for environment protection; and the ash content of after combustion is potash fertilizer with high quality, which can be returned to field for improving the soil.    DETAILED DESCRIPTION - A straw type coal comprises corn straw and plant straw comprising peanut shell, sear cauline leaf, paddy straw, wheat straw, or their mixture; where the weight ratio of corn straw and plant straw is 45-70:20-26 if the raw material components of the molded coal is corn straw and peanut shell or corn straw and sear cauline leaf; the weight ratio of corn straw and plant straw is 45-70:65-70 if the raw material components of the molded coal is corn straw and paddy straw; the weight ratio of corn straw and plant straw is 45-70:55-60 if the raw material components of the molded coal is corn straw and wheat straw; and the weight ratio of corn straw and plant straw is 45-70:20-26:65-70:55-60 if the raw material components of the molded coal is corn straw, peanut shell, sear cauline leaf, paddy straw, and wheat straw. An INDEPENDENT CLAIM is a production method of the straw-type coal comprising: (a) weighing the raw materials according to the weight ratio; (b) chopping and crushing each raw material component respectively, and uniformly mixing; (c) weighing the mixed raw materials; adding water that is 10-20% of the weight of the weighed raw materials to the weighed raw materials and uniformly stirring; and (d) extruding to obtain the straw-type coal.
