When the external load varies but the combustion condition of the heat cleaner remains unchanged, the ability of the heat cleaner's working fluid, heating surface, and furnace wall to release or absorb heat is referred to as the heat cleaner's heat storage capacity.
Imbalanced heat distribution refers to the phenomenon of uneven heat load within the same heated surface tube group. Imbalanced heat can be caused by both structural characteristics and operational conditions. This includes situations such as uneven distribution of flue gas temperature and velocity along the width of the flue; unevenly arranged or spaced serpentine tubes on the heating surface creating smoke corridors; ash accumulation and slag formation on the heating surface of a clean furnace, leading to an offset flame center in the furnace; and poor operational adjustments that cause flame deviation, downward shift, or upward lift, all of which contribute to imbalanced heat distribution.
Ensure steam parameters meet rated specifications and operate stably.
Ensure safe operation of heat cleaner furnaces and units under corresponding conditions.
3. Ensuring stable combustion, with a proper burning center, even flame distribution, and no damage to equipment, as well as preventing the accumulation of dust and焦。
The size of the heat storage capacity primarily depends on the working water volume of the heat cleaner and the amount of metal in the heating surface, and is also related to the steam pressure of the heat cleaner. In other words, the larger the working water volume and the more metal in the heating surface, the lower the steam pressure, the greater the heat storage capacity of the heat cleaner. For heat cleaners with heavy-duty walls, the heat storage also relates to the wall material.
