In the scheme 1 or 2, the bottom outside the furnace body is provided with the movable caster; or the fire observation mirror is arranged in front of the furnace body; or the smoke outlet is connected with an induced draft fan; or the bottom outside the furnace body is provided with a movable caster; or a fire observation mirror is arranged in front of the furnace body; or the smoke outlet is connected with an induced draft fan; or two downward inclined upright posts are symmetrically arranged on the inner wall surface of the bottom in the feeding hopper; or the outer wall surface of the feeding hopper is hung with a swinging heavy hammer.
The invention has the advantages that: 1. set up the dust fall basin below flue pipe right side lower extreme is uncovered for smoke and dust in the flue gas is subsided in the basin by the part in the boiler, and the flue gas of getting rid of is cleaner, does benefit to the environmental protection. 2. The water tank can be further sleeved in the dust falling water tank, the atomization effect is better when the smoke impacts the water surface, and the dust falling effect is improved. 3. The bottoms of the grooves are communicated, so that pollution discharge is facilitated. 4. The invention realizes the dust fall in the boiler and breaks the design of dust fall outside the conventional boiler body. In the past, the small boiler is not provided with dust removing equipment outside the body, smoke is directly discharged and polluted, and if the dust removing equipment is arranged, the cost is higher, and the small boiler is usually abandoned. Therefore, the invention adopts the dust fall in the body, realizes the forced reduction of the smoke dust from the source, has low cost, more convenient use, more practicability and very obvious comprehensive effect.
