Method for improving ash fusion point of sludge and coal mixed sample

The invention discloses a method for improving the ash fusion point of a sludge and coal mixed sample, which is characterized in that a fusion-resistant additive is added into the sludge and coal mixed sample, so that the ash fusion point of the mixed sample is improved. The ash fusion point can be regulated and controlled by regulating and controlling the doping proportion of the coal and the municipal sludge and the doping amount of the melting-resistant additive, the method is simple, convenient and easy to operate, the ash fusion point of the sludge and coal blended sample can be increased, the boiler combustion safety problem is reduced, the sludge blending combustion proportion can be increased, the coal use amount is reduced, and the cost is reduced. Meanwhile, sludge resource utilization is achieved, and the problem that sludge encircles a city is solved. 本发明公开了一种提高污泥与煤掺混样品灰熔点的方法，是在污泥与煤掺混样品中加入阻熔添加剂，从而提高掺混样品的灰熔点。本发明通过调控煤与城市污泥的掺杂比例以及阻熔添加剂的掺入量就能实现灰熔点的调控，方法简便易操作，既能提高污泥与煤掺混样品的灰熔点、减少锅炉燃烧安全问题，也能加大污泥掺烧比例、减少煤炭
