Industrial boiler body structure

The existing industrial boilers of our country can basically be divided into three types on the structure of heat receiving surface or “pot”: water pipe type, water fire pipe type and shell type (fire pipe type)

1. There are basically two types of water-tube boiler water-tube boilers: the drum is longitudinally arranged and the drum is horizontally arranged. The so-called longitudinal arrangement means that the axis of the drum along the length is in parallel with the line of sight of the person looking at the drum in front of the oven. The so-called transverse arrangement is that the axis of the drum in the longitudinal direction is in a vertical position with the sight of the drum from the front of the drum.

Typical double-tub vertical furnace, (SZL type) This type of furnace is also known as "D" type, its furnace furnace is characterized by the height of the combustion chamber and the overall height of the boiler shape close to full use and play a higher The combustion chamber is conducive to combustion, and the flue gas passes through the convective heating surface. A typical double drum horizontal chain furnace (SHL). This kind of boiler is suitable for larger capacity of more than 10 tons/hour. The flue gas flow is relatively uniform along the furnace width.

2. Water-fired boiler boilers Water-fired boilers are mainly made by adding water-cooled walls on the basis of horizontal external combustion and tempering furnaces. A typical water-fired quick chain furnace (KZL or DZL).

3, shell type boiler shell boilers in the past in the so-called fire tube category within the various types of boilers. Such as vertical cross-fire tube, horizontal water pipe, vertical bay water pipe, horizontal fire tube, horizontal external combustion and tempering pipe type, horizontal internal combustion fire tube boiler and so on.
