目前食堂用灶的灶型主要有两种:抽风灶和鼓风灶。这种灶的烟气中有大量热量流失,约占煤总发热值的40%。这是因为对灶型结构的系统设计和综合开发利用不够。而多功能、封闭式节能抽风灶弥补了这些缺陷。1、灰渣风道设有封闭门,实现了封闭情况下泄渣、捅火操作。消除灰渣外溢、灰尘飞扬的现象,保证了风道内的温度。2、独特的进风预热装置。进风口的位置打破了从灰渣风道膛直接进风的常规做法,而把进风口设置在距烧火间地面约两米高的烟筒上。烟筒为四方型,其中三侧设有铁板夹层,即进风预热腔Ⅰ,
At present, there are two kinds of cooking stoves in the canteen: ventilation stoves and blast stoves. This flue gas stove has a lot of heat loss, accounting for about 40% of the total calorific value of coal. This is because the system design and comprehensive development and utilization of the kitchen structure is not enough. The multi-functional, enclosed energy-saving stove to make up for these shortcomings. 1, ash duct with closed doors, to achieve the closed case of leaching residue, poke fire operation. Elimination of ash overflow, dusty phenomenon, to ensure the temperature inside the duct. 2, a unique air preheater. The position of the air inlet breaks the normal practice of direct air intake from the ash duct bore, while the air inlet is located on a chimney about two meters from the ground between fires. Chimney for the Quartet, with iron sandwich on three sides, that is, into the wind preheating chamber Ⅰ,
