Good variable pressure, standby and re-startup performances

锅炉下部炉膛水冷壁及灰斗采用螺旋管圈，在各种负荷下均有足够的冷却能力，并能有效地补偿沿炉膛周界上的热偏差，水动力特性稳定；采用四只启动分离器，壁厚均匀，温度变化时热应力小，适合于滑压运行，提高机组的效率，延长汽轮机的寿命。

The lower furnace waterwall and hopper adopt spiral coil and have enough cooling capacity under different loads, it can compensate the thermal deviation of furnace circumambience effectively, and the hydrodynamic force feature is stable; four startup separators are adopted, the wall thickness is even and the thermal stress is small when temperature changing, it is fit for sliding pressure operation, increase the unit efficiency and extend the life-time of turbine. (2) 采用大气扩容式启动系统

Adopted atmospheric flash type strat-up system

锅炉具有快速启动能力，缩短机组启动时间；系统简单、运行可靠。启动系统设置足够容量的大气式扩容器和疏水箱。

The boiler has the capacity of quick startup which can shorten the startup time. The startup system is simple and it can operation stably. The system equipped with atmosphere type flash tank and water tank which has enough capacity. (3) 燃烧稳定、温度场均匀的新型切圆燃烧系统

New type tangential combustion system which has stable firing and uniform temperature field

新型切圆燃烧系统燃烧方式能保证沿炉膛水平方向均匀的热负荷分配。这种强化型单切圆因煤粉气流垂直于水冷壁，且大切圆使炉膛内火焰充满度好，对于保证燃烧稳定性有利，与角式布置的燃烧器相比，具有火焰行程短，火焰两侧补气条件好等优点。

New type tangential combustion system can guarantee heat distribution along horizontal furnace is uniform. The pulverized coal flow of this reinforced single tangential is vertical to water wall and big tangential makes the furnace flame fullness is good, and it is good for guarantee the stable combustion.

This boiler combines mature design and manufacture experience of some boilers with good operation reference, the usability and reliability of the unit is high which can meet different technical requirements of the customer. 3.2 结构特点 Structural features

(1) 本锅炉中、下部水冷壁采用螺旋管圈，上部水冷壁采用一次上升垂直管屏，二者之间用过渡集箱连接。螺旋管圈的同一管带中的各管子以相同方式从下到上绕过炉膛的角隅部分和中间部分，同时螺旋管圈的旋转上升方向与燃烧器的火焰切圆旋转方向相反，水冷壁吸热均匀，管间热偏差小，使得水冷壁出口的介质温度和金属温度非常均匀。因此，螺旋管圈水冷壁可以适应炉内燃烧工况的变化。

The middle and lower waterwall of furnace adopts spiral coil, upper waterwall adopts primary upward vertical panel, and the two are connected by transition header. Different tubes in one tube belt of spiral coil are around furnace corner zone and middle zone from down to up in same method, and the rotary direction of spiral coil is opposite to the rotary direction of burner flame tangent, the waterwall heat absorbing is uniform, heat deviation between tubes is small, that makes waterwall outlet medium temperature and metal temperature very uniform. So spiral coil waterwall can suit the changes of furnace combustion condition.

(2) 在螺旋管圈水冷壁部分采用可膨胀的带张力板垂直刚性梁系统，螺旋管圈的悬吊是由均匀附着于管壁外表面的张力板实现的。张力板从冷灰斗的底部一直布置到螺旋管圈和垂直管屏的过渡区，在过渡区把重量荷载通过梳形吊板均匀地传给上部垂直管屏。刚性梁体系及炉墙等的自重荷载完全由垂直搭接板支吊，下部炉膛和冷灰斗的荷载能传递给上部垂直水冷壁。刚性梁和水冷壁之间相互不直接焊接，可以相对滑动，以防止附加热应力的产生，保证炉膛安全可靠运行。

The expandable vertical buckstay system with strap is adopted in spiral coil waterwall part; the hanging of spiral coil is realized by the strap which equably adheres on the outer surface of tube wall. The strap is arranged from hopper bottom to the transition zone of spiral coil and vertical panel, in the transition zone the weight load is passed to upper vertical panel uniformly by comb plate. The dead-load of buckstay system and furnace is totally hanged by vertical lap jointed sheeting, the load of lower furnace and hopper can be passed to upper vertical waterwall. Direct weld could not be taken between buckstay and waterwall, relative slide is permitted to prevent additional thermal stress and guarantee furnace reliably operation.

(3) 为了保持过热器和再热器部件的横向节距和防止晃动，采用以下蒸汽冷却夹管和间隔管结构：

In order to keep the transverse pitch of SH and RH parts and to prevent vibration, following steam cooling girder tube and spacer tube structures are adopted:

蒸汽冷却夹管用于保持分隔屏的横向节距，防止分隔屏过分偏斜，其流程如下:

Steam cooling girder tube is used to keep the transverse pitch of division panel to prevent excessive deviation. The flow chart is as follows:

分隔屏入口集箱→蒸汽冷却夹管入口管→蒸汽冷却夹管定位管→蒸汽冷却夹管出口管→末级过热器出口集箱。

Division panel inlet header→steam cooling clamp tube inlet tube→steam cooling clamp tube locating tube→steam cooling clamp tube outlet piping→final SH outlet header

蒸汽冷却间隔管用于保持分隔屏过热器、末级过热器和末级再热器的横向节距，防止末级过热器和末级再热器过分偏斜，其流程如下:

Steam cooling spacer tube is used to keep the transverse pitch of division SH, final SH and final RH to prevent excessive deviation. The flow chart is as

follows:

Chart1 Steam cooling girder tube

立式低过出口连接管→分隔屏过热器区域蒸汽冷却间隔管→末级过热器入口集箱。

Vertical low-temp SH connecting pipe→ steam cooling spacer tube of division SH → final SH inlet header

立式低过出口连接管→末级过热器区域蒸汽冷却间隔管→末级过热器入口集箱。

立式低过出口连接管→末级再热器区域蒸汽冷却间隔管→末级过热器入口集箱。

Vertical low-temp SH connecting pipe→ steam cooling spacer tube of final RH → final SH inlet header

(4) 锅炉设有二级减温水喷水旁路系统，其作用是在锅炉直流负荷以上，由于暖管流量造成贮水箱内水位升高时可将水引入过热器减温水系统，喷入过热器，在需要时控制贮水箱水位。

The boiler is equipped with secondary stage desuperheating water spray bypass system, its function is it can inject water to SH desuperheating water system directly when the water level of storage tank increasing caused by the warm pipe flow under the load above the boiler once-through load, and can inject to SH and control the water level of storage tank if needed.

(5) 过热器为辐射对流型，低温过热器布置于尾部竖井后烟道，分隔屏过热器和高温末级过热器布置于炉膛上部。过热蒸汽温度采用煤水比和两级喷水减温控制。在上炉膛布置横向节距较宽的分隔屏受热面，有效防止管屏挂渣。

The superheater is radiation-convection type, low-temp SH is arranged in back pass back duct, division SH and high-temp final SH are arranged in furnace upper part. Superheated steam temperature is controlled by coal-water ratio and two-stage spray desuperheater. The division panel heating surface with wide transverse pitch is arranged in upper furnace, it can prevent panel slagging effectively.

(6) 高温再热器布置于水平烟道，低温再热器布置于尾部竖井前烟道，再
