火力发电厂皮带中部采样机应用实践

Application practice of belt middle sampler in thermal power plant

随着“三个转变”促进质量效益双提升,中国制造逐步向中国创造转变,中国速度逐步向中国质量转变,在全国树立“质量即是生命、创造即是效益”的大环境下,火电企业也面临着历史上前所未有的挑战。火电企业只有全面加强质量管理,才能增强企业竞争力,而燃料成本占火电厂发电成本的80%左右。煤炭的采样误差占燃煤采制化总误差的80%,将燃料管理信息化与皮带中部采样机应用在入厂火车煤验收之中,采样代表性得到充分体现,厂炉热值差也得到控制。

With the“three changes”to promote the quality benefit double promotion,made in China to created in China step by step,China speed gradually to the Chinese quality,across the country to establish“quality is life,creating is the benefit”of the environment,thermal power enterprise is faced with the unprecedented challenges in history.Only by strengthening quality management can thermal power enterprises enhance their competitiveness.However,the fuel costs account for about 80% of power generation costs in thermal power plants the sampling error of coal accounts for 80% of the total sampling error of coal.The fuel management information and belt sampler are applied in the acceptance of coal on the incoming train,the sampling representativeness is fully reflected,and the difference of heating value of the furnace is also controlled.
