Description
DZL series water fire tube steam boiler
1.COOL THE HIGH TEMPERATURE TUBE SHEET TO AVOID SUBCOOLED BOILING,LOWER THE HEAT LOAD OF THE BOILER BOTTOM,AVOID THE CRACK OF THE TUBE SHEET,AVOID THE DEFORMATION OF THE BOTTOM.
2.MAKE THE TUBE SHEET MORE FLEXIBLE TO LOWER THE TUBE END WELD HEAT STRESS.CANCEL BRACING PIECES TO AVOID THE CRACK OF THE TUBE SHEET.
3.ENHANCE HEAT TRANSFER ,REDUCE THE SIZE OF THE POT, MAKE IT MORE FLEXIBLE TO TOWER THE TUBE ENDAND HEAT STRESS, AVOID FOULING,AVOID THE CRACK OF THE TUBE SHEET.
