The invention discloses a
far infrared heat-
pipe steam-water dual-purpose
heating furnace, pertaining to the field of
heat energy. The
far infrared heat-
pipe steam-water dual-purpose
heating furnace comprises a clinker chamber (1), a
coal charging gate (2), a secondary blast
pipe, a
tuyere (3), an inner boiler drum (4), an external boiler drum (5), a furnace discharging pipe, a collecting box (6), a horizontal water-cycle pipe (7), a deformed high-temperature
heat pipe (8), a steam collecting and distributing cylinder (9), a main steam-supply pipe, a
flue-gas tube (11), a heat-pipe preheating water tank (12), a dust-preventing deformed moderate-temperature
heat pipe (13), a dust cleaning door, a blow-off pipe (15), a
far infrared high-temperature
radiation energy-saving dope (16), an
electrode drum, a
fluid level gage (17), a short-water alarming
electrode (18), an electromagnetic
float switch (19), a water-replenishing pipe (20) and a blower (21). The secondary blast pipe and
tuyere (3) are arranged above the
coal charging gate (2); the deformed high-temperature
heat pipe (8) is arranged in the furnace; the heat-pipe preheating water tank (12) and the dust-preventing deformed moderate-temperature heat pipe (13) are arranged at a
flue-gas outlet; the far
infrared high-temperature
radiation energy-saving dope (16) is coated on the
metal surfaces of the inner boiler drum (4), the furnace discharging pipe and collecting box (6), the horizontal water-cycle pipe (7), the deformed high-temperature heat pipe (8), the heat-pipe preheating water tank (12) and the dust-preventing deformed moderate-temperature heat pipe (13). The deformed high-temperature heat pipe (8) arranged in the furnace reclaims the high temperature
flue gas produced during burning into the furnace. The heat-pipe preheating water tank (12) and the dust-preventing deformed moderate-temperature heat pipe (13) arranged at the flue-gas outlet jointly prevent dust and flue-gas from transgressing.
