Gas improves air themperature, realizes that the air to preheating of air, after preheating is input to burner by air inlet pipe (31)
(3), reduce thermal losses makes natural gas full combustion simultaneously；Last flue gas is arranged by the exhanst gas outlet of flue gas heat-exchange tube (62)
Out；
After the water in natural gas steam boiler body (1) reaches boiling point, the upper lateral screw conveyor (41) of duration starting
Conveying is carried out to water with lower lateral screw conveyor (42) and forms circulating water, inclination water fender belonging to each water blocking plate (43)
(431) circulating water is stopped to change its flow direction respectively, so that circulating water constitutes vertical rectangle water and circulates frame
(100), to promote the water evaporation in natural gas steam boiler body (1), evaporated quantity of water and water evaporation efficiency are improved, water steams
Gas is transferred out by the steam conveying pipe that steam outlet (10) is installed.
