Description

A kind of biomass steam generator

Technical field

The utility model relates to the steam generator field, particularly relates to a kind of biomass steam generator.

Background technology

Biomass energy is the important energy source that the mankind depend on for existence always, and it is to be only second to coal, oil and natural gas and the energy that occupy the 4th of world energy sources total quantity consumed, occupies critical role in whole energy resource system.Relevant expert's estimation, biomass energy very likely becomes the part of following sustainable energy system, and to the middle of this century, the various biomass substitute fuels of producing of employing new technology will account for more than 40% of global total energy consumption.

The biomass steam generator is that the employing biomass fuel is the steam generator of raw material, and it has the advantages such as pollution is low, and raw material is renewable and widely distributed, more and more is subject to the attention of society in industry, civilian production.Present biomass steam generator adopts the structure of single fire grate mostly, exists a series of shortcoming, as: burn insufficient, burn-off rate is undesirable, etc., caused the waste of resource.

The utility model content

The technical problem that the utility model mainly solves provides a kind of biomass steam generator, can improve burn-off rate and the thermal efficiency of biomass steam generator.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of biomass steam generator is provided, comprises: high temperature resistant housing, vaporization chamber, the steam (vapor) outlet of vaporization chamber top, the water-level gauge in the vaporization chamber, pass the chimney of vaporization chamber, the economizer that connects chimney, the combustion chamber of vaporization chamber below, the pay-off of connection combustion chamber, blower fan, ring baffle in the combustion chamber, the ash discharging hole of bottom, combustion chamber, the base of below, combustion chamber.

In preferred embodiment of the utility model, described biomass steam generator adopts the double grate structure.

In preferred embodiment of the utility model, inside, described combustion chamber includes upper fire-grating and lower fire grating, and the combustion chamber is divided into the combustion chamber, preheating chamber and deashing chamber.

In preferred embodiment of the utility model, described upper fire-grating and lower fire grating all adopt resistant to elevated temperatures basalt fibre as material.

In preferred embodiment of the utility model, the heat exchanger tube that connects vaporization chamber is equipped with in described chimney inside.

The beneficial effects of the utility model are: the utility model adopts the double grate structure, can improve the burn-off rate of fuel, makes burning more abundant, has improved the thermal efficiency of steam generator.

The mark of each parts is as follows in the accompanying drawing: 1, vaporization chamber, 2, the combustion chamber, 3, preheating chamber, 4, high temperature resistant housing, 5, pay-off, 6, blower fan, 7, ring baffle, 8, upper fire-grating, 9, lower fire grating, 10, deashing chamber, 11, ash discharging hole, 12, heat exchanger tube, 13, water-level gauge, 14, steam (vapor) outlet, 15, economizer, 16, chimney, 17, base.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.

Be illustrated in figure 1 as the profile of a kind of biomass steam generator of the utility model, comprise: high temperature resistant housing 4, vaporization chamber 1, the steam (vapor) outlet 14 of vaporization chamber top, water-level gauge 13 in the vaporization chamber passes the chimney 16 of vaporization chamber, connects the economizer 15 of chimney, the combustion chamber 2 of vaporization chamber below, the pay-off 5 that connects the combustion chamber, blower fan 6, the ring baffle 7 in the combustion chamber, the ash discharging hole 11 of bottom, combustion chamber, the base 17 of below, combustion chamber.

Further, described biomass steam generator adopts the double grate structure.

Further, inside, described combustion chamber includes upper fire-grating 8 and lower fire grating 9, and the combustion chamber is divided into combustion chamber 2, preheating chamber 3 and deashing chamber 10.Upper fire-grating adopts larger slot, less particle can be leaked on the lower fire grating, lower fire grating adopts less circular hole, make after the fuel combustion ash can after be put in the deashing chamber, the particle burning of upper fire-grating provides heat for vaporization chamber, the particle burning of lower fire grating plays the effect of a preheating to the particle of upper fire-grating, improved the speed of firing of combustion chamber granular fuel.

Further, described upper fire-grating 8 and lower fire grating 9 all adopt resistant to elevated temperatures basalt fibre as material.

Further, the heat exchanger tube 12 that connects vaporization chamber is equipped with in described chimney 16 inside, the exhaust temperature that the steam generator burning is emitted is higher, some heat exchanger tubes that communicate with vaporization chamber of the inner installation of chimney, realize the conversion of exhaust temperature, the use of economizer 15 has further reduced the temperature of tail gas, has improved the thermal efficiency.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
