Grate Bar For Boiler
Incineration grate by fixed grate, sliding grate and turning grate three kinds of grate, unique turning grate design make grate not only has the usual reciprocating movement function, but also has the turning function, strengthen the garbage mixing, loose, ventilation, the low calorific value, high moisture characteristics of waste incineration has certain advantages, make the slag heat reduction rate control in <3%.
The whole incinerator grate is divided into five grate area groups. Each standard grate group consists of two sliding grate, two turning grate and two fixed grate, and six hydraulic cylinders to complete the movement and turning function of garbage. The sliding grate sheet moves horizontally to ensure that the garbage combustion layer moves forward in the horizontal direction and moves forward to ensure that the garbage layer moves over. The speed and frequency of each group of furnaces can be controlled separately, which improves the adaptability of the incinerator to the domestic waste with a large calorific value fluctuation range. In addition, the operation can be completely stopped when necessary, and the reaction process of drying, heating, decomposition, burning and burning of the garbage on the incineration furnace can be better controlled. In the incineration of garbage with high calorific value, the ratio of turning and sliding times is preset in the control system to reduce the action frequency of each group of turning the furnace grate, and reduce the residence time of garbage on the garbage grate, so as to ensure the amount of garbage treated by the incinerator.
The width of the grate is 300 mm, with 17 grate rows, and the total width of the incineration grate is 5100mm. The total length of the incinerator grate is m, the first four units are the combustion section, and the last unit is the burning area. In order to ensure the full incineration of garbage, the thermal reduction rate of the incinerator is controlled at <3%, so as to meet the relatively strict technical requirements, so the last section should be extended appropriately lengthened.
The air inlet of the bottom part of the grate chamber optimizes the combustion air supply and extends the service life of the grate. The ash bucket at the lower part of the grate can not only collect the ash at the bottom of the furnace, but also be the primary air inlet of each grate group. The primary air enters the incinerator along the grate group and blows down to the garbage material layer, which not only effectively reduces the coking of the garbage surface, but also cools the grate sheet well and reduces the replacement rate of the grate. In addition, the grate selection of high quality materials, as well as the precise coordination of each moving parts, the grate piece has a high durability.
