摘要

FIELD: construction.;SUBSTANCE: invention relates to the field of construction of dumps of ash and slag materials of thermal power plants, heating boiler houses and may be used to erect drained slag dump without raised dams and settling pond. For this purpose prior to cold season of the year, without termination of slag inwash, on surface of slag dump under exhaust nozzles of pulp line there are distribution collapsible trays installed on supports together with covering frame-shield galleries with inlet hatches, afterwards surface of slag dump and galleries are coated with heat insulation screen. Galleries are filled in direction from their end to their beginning. Winter inwash of slag is carried out until previously washed slag freezes under heat insulation screen. On completion of cold period, heat insulation screen, frame-shield galleries and collapsible distribution trays are dismantled and stored for use in the following cold period of the year. Slag inwash in summer period is resumed after thawing of frozen layer of slag.;EFFECT: extension of slag inwash period.;3 dwg
