Embodiment

Body of heater of the present invention is a current techique, gas fume after burning is passed the lower smoke chamber that smoke through hole enters the U-shaped heat exchanger from slag trapping chamber, upwards enter upper smoke collecting chamber through right smoke exhaust pipe, enter lower smoke chamber's leftward space at interval downwards through the left bank smoke pipe again and enter smoke exhaust pipe, upwards enter atmosphere through after the last heat exchange, the lower smoke chamber of the flue dust of carrying secretly in flue gas natural subsidence in the heat transfer process of the U-shaped heat exchanger of last lower smoke chamber and smoke pipe composition, the cigarette ash of deposition is regularly discharged by cleaning door, owing to have bigger heat exchange area, thereby have good heat exchange effect and environment protecting.

The effect that fire door 4 and following fire door 3 are set is can add more coal by two crossings, and overcoming conventional boiler needs ceaselessly stoking drawback, adds a dant and can burn for a long time, during igniting, fill it up with coal by two fire doors up and down, ignition substance is put into by last fire door, after lighting, close upper furnace door, air-introduced machine is discharged fume by smoke exhaust pipe, enters air by blast pipe, burning from top to bottom after coal is lighted, slag falls into slag trapping chamber by the slit between the tubular type fire grate, regularly clears up by slag notch.Owing to be anti-burning, the coal that newly adds is at the upper furnace preheated burning, so flue dust burns through the high-temp combustion grate firing downwards, the flue gas that enters except that the grit chamber does not contain flue dust substantially, so the smoke abatement effect is better than other positive burning boilers, compliance with environmental protection requirements.

The heating medium was a water when heat exchanging water-jacket did the hot water space heating boiler use, if with warm braw heating, such as being drying chamber, greenhouse or green house of vegetables thermal source, warm braw can be provided, replace aqueous medium with air dielectric, make the heating medium with air, heat exchanging water-jacket and U-shaped heat exchanger can use the aluminium alloy extrusions processing and fabricating, can improve the heat exchange effect greatly like this.
