FIELD: building materials, heat power engineering, production of ash-carrying building materials, control over lignite burning process at power-and-heating plants. SUBSTANCE: method establishing content of losses Lcal in process of calcination in lignite ash employs dependence determined beforehand with use of indirect characteristic-index Tn of normal thickness of ash putty and residue R, after screening lignite ash through sieve with hole diameter of 80 mu. Regression of double parametric dependence of Lcal on Tn and R expressed in the form of equation is used to determine content of losses in process of calcination. This equation can have this form: Lcal = 0,4420R+0,642-0,015Tn. EFFECT: increased accuracy of determination of losses in process of calcination in lignite ash. 1 cl, 2 tbl |
