Height and position at corresponding observation panel is provided with a closed sandwich along inboard wall of furnace body, the inwall of this interlayer has a plurality of steam vents that lead to the center, this interlayer some air inlet pipe outer with being arranged at body of heater communicate, and this air inlet pipe hangs down to outside body of heater near ground and with atmosphere and communicates.

Described pressure vessel is provided with feeding cover, vent valves and liquid level indicator.

The utility model has following actively useful effect:

1, can on the basis that original hot-water boiler, drinking water boiler do not change, transform, be easy to promote.

2, reduce SO ₂Concentration of emission is up to state standards.

After testing: this stove is in heating process

(1) ignition phase: through desulfurizer SO ₂A concentration maximum of concentration of emission 85.78mg/Nm ³A minimum of a value 77mg/Nm ³, three daily mean 80.78mg/Nm ³, all be lower than GB9078-88 secondary 850mg/Nm ³Standard desulfurized effect 96%.

(2) temperature rise period: SO ₂Maximum 74.00mg/Nm of concentration of emission ³, a minimum of a value 69.00mg/Nm ³, three daily mean 71.55mg/Nm ³, all be lower than GB9078-88 secondary 850mg/Nm ³Standard desulfurization degree 96%.

(3) constant temperature stage: SO ₂A maximum 65.00mg/Nm ³, a minimum of a value 60.00mg/Nm ³, three daily means, 6 2.00mg/Nm ³, all be lower than GB9078.88 secondary 850mg/Nm ³Standard.

(4) this stove is in whole heating process, and total concentration value on the three is 71.44mg/Nm in the production cycle ³, all be lower than GB9078-88 secondary 850mg/Nm ³The standard desulfurized effect reach 93%.
