生物质电厂炉前给料系统输送不顺畅解决方案

摘要:利用生物质发电目前在全国是一个新兴的发电行业，中国是一个农业大国，生物质能源在我国农村资源相当丰富。主要的农作物种类有稻谷、小麦、玉米、豆类、薯类油料作物、棉花和甘蔗。各种农作物每年产生秸秆6亿多吨，其中可以作为能源使用的约4亿吨，全国林木总生物量约190亿吨，可获得量为9亿吨，可作为能源利用的总量约为3亿吨。如加以有效利用，开发潜力将十分巨大。但是生物质电厂的发电运行和炉前给料系统的安全经济运行息息相关。但是目前我国各家生物质电厂的炉前给料系统都不成熟，主要是在输送散状秸秆方面都存在缠绕、给料不顺畅的问题。河北新能电力有限公司作为生物质电厂的投资者，为了以后在电厂的安全经济运行，未雨绸缪，针对炉前给料系统进行了大胆的创新，并且受到良好的运行效果，本文就生物质电厂炉前给料系统的运行特点及极易出现的问题提出了有效的解决方案，此系统的应用必将我国的生物质发电项目推向前进。

Abstract:The use of biomass power generation in the country is an emerging power generation industry, China is a large agricultural country, biomass energy resources in China is abundant in rural areas. The main types of crops are rice, wheat, corn, beans, potato oil crops, cotton and sugar cane. A variety of crops each year, more than 600 million tons of straw, which can be used as a source of energy of about 400 million tons, the National Forest the total biomass of about 19 billion tons, the availability of 900 million tons, can be used as the total energy use is about 3 million tons. Such as effective use of them, an enormous potential for development. However, biomass power plant operation and steel feeding system is closely related to the safe and economic operation. However, each of China’s steel plant biomass feeding system is not mature, mainly in the bulk transportation of straw are the existence of entanglement, not smooth feeding problems. Hebei Power Co., Ltd. as a new biomass power plant investors, in order after the safe and economic operation of power plants and take precautions against steel feeding system to carry out a bold innovation, and run by good results, this article on biomass steel plant feeding system and the operating characteristics of the problem can easily make an effective solution,Application of this system is bound to China’s biomass power generation project to move forward.

Key words: steel feeder, screw conveyor, winding, smooth and economical.

1、秸秆发电的前景

农作物秸秆是一种很好的清洁可再生能源，每两吨秸秆的热值就相当于一吨标准煤，而且其平均含硫量只有3.8‰，煤的平均含硫量约达1％。在生物质的再生利用过程中，排放的CO2与生物质再生时吸收的CO2达到碳平衡，具有CO2零排放的作用，市场前景非常广阔。
