2.Main character:

2.1Structural character

The waste heat boiler is outdoor horizontal smoke tube boiler and is composed of boiler shell and inlet & outlet smoke box. Gas is diverted by inlet smoke box and washes smoke tube in vertical direction and finally converges and flows out from outlet smoke box. In order to avoid a direct wash to front tube sheet by high-heat gas, a refractory protection is cast on the surface of front tube sheet and a refractory protective tube is installed on the inlet of the smoke tube. Steam space is located on the upper part of boiler shell smoke tube, and a wire mesh demister is installed on the steam outlet for steam-water separation. The whole waste heat boiler is supported by two saddles; one along the direction of the gas flow is fixed support and is fixed on the foundation by eight anchor bolts, others are sliding supports.
