Description

Household square briquette boiler without pressure and smoke

The utility model belongs to the domestic boiler technical field, is that a kind of square nothing is pressed smokeless household coal burning boiler.

At present, existing life, is found that in use still existence burning is insufficient and is made, uses inconvenient deficiency though some advantage is arranged with the boiler of briquet.

The purpose of this utility model is, provides a kind of square nothing to press smokeless household coal burning boiler, makes it specially burn moulded coal, has sufficient combustion, do not have in the boiler and presses, makes advantage simple, easy to use.

The technical scheme that the utility model is finished goal of the invention is: boiler is horizontal, housing (2) is square, flue (4) is installed in the housing (2), several circulating water pipes (3) are installed in the flue (4), and installation fire grate (7), moulded coal carriage (20) is installed on the top of housing (2), in housing (2) bottom, there is fire door (6) moulded coal carriage (20) below, fireguard (18) is installed in the flue (4), firebreak (16), (21), (17) and (19) are installed respectively on the circulating water pipe (3).Fluting (24) on the baseplane that moulded coal carriage (20) is interior with moulded coal contacts.

Description of drawings: accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is left views of accompanying drawing 1;

Accompanying drawing 3 is bottom views of moulded coal carriage (20) in the accompanying drawing 1, mainly illustrates the shape of groove (23).

The contrast accompanying drawing is described further the utility model embodiment:

(2) are housings among the figure, flue (4) is installed in the housing (2), several circulating water pipes (3) are installed in the flue (4), circulating water pipe (3) is gone up firebreak (16) is installed, firebreak (16) is in the top of flue (4), the inwall on firebreak (16) one ends and flue (4) left side joins, the other end water receiving pipe of firebreak (16).In firebreak (16) below fireguard (18) and firebreak (21) are installed, the upper end of firebreak (21) connects firebreak (16), the lower end connects firebreak (19), firebreak keeps off into burner hearth high-temperature region (23) in flue (4), one end of firebreak (17) and flue (4) the right inwall join, and the other end and water pipe join.Moulded coal carriage (20) is installed on the top of housing (2), and there is fire door (6) housing (2) bottom, moulded coal carriage (20) below, and flue (4) bottom installs and fixes fire grate (7).When the utility model uses, put into moulded coal, after the ignition, open fire door (5) moulded coal is put into carriage (20), in burner hearth, replenish moulded coal at regular time and quantity from fire door (6).Have groove (24) on the baseplane that moulded coal carriage (20) is interior with moulded coal contacts, this groove (24) can be an elongate slots.Moulded coal carriage (20) separates moulded coal respectively, owing to have groove (24) on carriage (24) baseplane, makes flame and high temperature in the burner hearth directly import moulded coal into, plays preheating, and emits the effect of fugitive constituent gradually.Fireguard (18) in the dead ahead of moulded coal carriage (20), can help the preheating moulded coal, and can make flue gas through the high-temperature region (23) downwards, make the abundant afterburnt of fugitive constituent enter the firebreak zone of circulating water pipe (3) again from furnace outlet (22), flue gas enters chimney (1) through firebreak (19), (17), four backhauls of (16) folding, has reached the purpose of thorough elimination black smoke.(8) are the stove seats among the figure, and (9) are the ash doors, and (10) are steam outlet pipes, and (11) are breather pipes, and (12) are the water level meters, and (13) are thermometers, and (14) are the boiling water outlets, and (15) are water inlets.

The utility model has sufficient combustion through using proof, not over-emitting black exhaust, manufacturing advantage simple, easy to use.
