The furnace liner is the combustion chamber of the horizontal gas-fired heat transfer oil furnace. The burner nozzle is placed in the front of the furnace liner, and the high-temperature flue gas generated by combustion extends to the rear, leaving the furnace liner and returning to the space. Generally, the number of times of returning is not more than four, and the common one is the three return heat conduction oil furnace. Heilongjiang Fuel oil steam generator This type of heat transfer oil furnace can be divided into dry back type heat transfer oil furnace and full wet back type heat transfer oil furnace according to the structure of the flue gas reentry space at the rear of the furnace. The flue gas reentry space of the dry back heat conduction oil furnace is enclosed by refractory materials; The flue gas reentry space of the full wet back type heat conduction oil furnace is composed of a recuperative chamber immersed in water. In addition, there is a central regenerative heat conduction oil furnace: that is, the back wall of the furnace liner is sealed inside the boiler shell, and the flue gas is turned back to the front from the inner wall around the furnace liner after encountering. This type of heat transfer oil furnace can also be regarded as a full wet back heat transfer oil furnace. vertical Fuel oil steam generator factory Although the dry back heat transfer oil furnace is simple in structure, the refractory material at the rear of the furnace liner is easily damaged, and the rear tube plate is often directly washed by high temperature flue gas. The temperature difference is large, so the dry back heat transfer oil furnace is obsolete. At present, few manufacturers produce it; Although the full wet back heat conduction oil furnace has a complex structure, it avoids the problem of flue gas sealing in the reentry space and is suitable for micro positive pressure combustion.

When using stainless steel storage tank, cracks appear on the head. If it is not handled in time, it will be dangerous, and how to handle this situation will be explained.
