直流,单炉室,微正压324型锅炉机组的设计出力为1000吨/时,过热汽温545/545℃,当燃用M100号重油时,设计效率94.7%。为保证锅炉机组以设计的炉膛压力(310公斤力/米~2)运行,装了两台548·10~3标准米~3/时,800公斤力/米~2的25×2型送风机。为了提高安全性和保证锅炉机组的持续运行,又装了两台745·10~3标准米~3/时,360公斤力/米~2的备用引风机。采用了两套密封系统来保证锅炉机组的气密性(图1)。所有炉膛,转弯烟道和对流井管屏都用直径32×6毫米的管子构成全焊接的,称为内密封1的匣子。外密封包括烟气有可能经内密封漏出处的密封箱:炉顶的炉罩2,炉膛内下辐射-中辐射和中辐射-上辐射连接处的周围密封箱3,在这些地方都送入来自再生式空气预热器后的密封空气。
The designed output of direct current, single-chamber and micro-positive pressure 324 boiler units is 1000 tons / hour and the superheated steam temperature is 545/545 ℃. The design efficiency of 94.7% when using M100 heavy oil. To ensure that the boiler unit operates at the designed hearth pressure (310 kgf / m ~ 2), two 25 × 2 blowers with 548 · 10 ~ 3 standard meters ~ 3 / hour and 800 kgf / m ~ 2 are installed. In order to improve safety and ensure the continuous operation of the boiler unit, they are equipped with two standby draft fans of 745 · 10 ~ 3 standard meters ~ 3 / hour and 360 kgf / m ~ 2. Two sealing systems are used to ensure the airtightness of the boiler unit (Figure 1). All furnaces, turn flue and convection well screens are fully welded with a tube of 32 x 6 mm diameter called box 1 of inner seal. The outer seal consists of a sealed box where flue gas may leak through the inner seal: the furnace hood 2 at the top of the furnace, the lower radiation in the hearth - the surrounding sealed boxes 3 at the mid-radiation and upper radiation connections where they are fed Sealed air from regenerative air preheater.
