Steam boiler with grate firing burning mix coal and wood (mixing ratio 30/70-wood)

By Aleš Dvořák


This diploma work attends to presentation of steam grid boiler for wood and brown coal burning in scale (30/70-wood) in load 60t/h, with parametres of outgoing vapour p=7MPa, t=490°C. The work is splitted to several chapters. At the beginning I’m going to make stechiometric calculation and entalpic calculations of air and compustion gas. After that I’m going to calculate heat balance, losses of boiler and set heat efficiency of boiler. Then I’m going to suggest combustion chamber of boiler and make heat calculation. After suggestion of combustion chamber I’m going to set proportions of pulls and heat-delivery surface. In last chapter I’m giong to check heat balance. Inclosure of my work contains drawing documentation of steam boiler
