发明名称 Steam generation boiler
摘要 A steam generation boiler having a reaction chamber formed by a bottom portion in a lower portion, a roof portion at an upper portion, and walls extending vertically between the bottom portion and the roof portion. The walls include vertical end walls having a tapering wall section that tapers symmetrically with respect to its middle axis towards the bottom portion, in which (i) a first group of steam pipes in the tapering wall section including steam pipes on both sides of the middle axis, pass at an angle with respect to the middle axis in a wall plane of the tapering wall section, and from the wall plane into the reaction chamber, and (ii) a second group of steam pipes arranged to pass to the bottom portion along the wall plane.

主权项 1. A steam generation boiler having a reaction chamber, the steam generation boiler comprising: a bottom portion in a lower portion of the steam generation boiler; a roof portion at an upper portion of the steam generation boiler; and walls extending vertically between the bottom portion and the roof portion, thus forming the reaction chamber of the steam generation boiler, the walls comprising vertical end walls and embodying a structure comprising steam generator pipes, the vertical end walls comprising a tapering wall section that tapers symmetrically with respect to its middle axis towards the bottom portion of the steam generation boiler, wherein (i) a first group of steam pipes in the tapering wall section, comprising steam pipes on both sides of the middle axis, is arranged to pass at an angle with respect to the middle axis in a wall plane of the tapering wall section, and from the wall plane into the reaction chamber, to extend from the wall plane to the bottom portion of the steam generation boiler on a side of the reaction chamber forming a wall in the reaction chamber, wherein the steam pipes of the first group pass from the wall plane of the tapering wall section to the bottom portion of the steam generation boiler in two different subgroups on different planes that are separated by a distance from one another, and the distance is such that the first subgroup and the second subgroup are gas-tightly separated from the reaction chamber by a space that is arranged between the first subgroup and the second subgroup, and (ii) a second group of steam pipes is arranged to pass to the bottom portion along the wall plane.
