Abstract
The invention discloses a biomass fuel hot-water boiler, aiming at improving the ignition conditions of biomass fuel, shorten combustion start time, realize complete combustion and increase heat exchange efficiency. The hot-water boiler comprises a hearth (1), a boiler arch (2), a boiler door (4), a grate (3), a hopper (15) and a high-temperature flue communicated with the hearth (9). A hot water heating pipe (7) is arranged in the high-temperature flue (9) circuitously. A fixed ladder grate (10) at an angle with the water level is arranged in the hearth (1) and provided with a material pushing block (12) at the upper end; the bottom of the fixed ladder grate (10) is provided with a blower (6); and the vertical direction where the inside of the hearth (1) is opposite to the fixed ladder grate (10) is provided with a section of arch-shaped boiler arch (11). Widely applied to the field of solid fuel boiler units, the biomass fuel hot-water boiler reduces manufacturing cost and improves economic benefit.
Description
Technical field
The present invention relates to solid-fuelled combustion apparatus, particularly relating to living beings is the water heater of fuel.
Background technology
Coal mainly is used as boiler oil as first energy in China's energy resource structure, for a long time, and insufficient, the phenomenons such as the thermal efficiency is low, the wasting of resources is severe, major polluting atmosphere environment of coal-burning boiler equipment ubiquity burning.Because the flue dust of discharged from coal-fired boiler destroys environment, in the city, have been prohibited or limit use, force the operator to use the boiler plant of fuel oil or combustion gas instead, and the continuing to raise up and make that the operator is difficult to bear of oil price; Day by day exhausted along with the increasingly serious and fossil fuel of environmental protection trend, human " the increasing income and decreasing expenditure " that must realize the energy, that is: one is the efficient that improves fuel combustion reducing consumption, and realizes that simultaneously clean burning is with the minimizing environmental pollution; The 2nd, tap a new source of energy, and actively utilize regenerative resource.Biomass energy is that solar energy is transformed by photosynthesis, and mainly the form with farm-forestry crop exists, and is a kind of unique reproducible carbon source.China's biomass resource is very abundant, there is the wooden matrix rubbish in a large amount of agriculture and forestry organic waste materials, fuel wood woods, wood-curing waste, building decoration building site available, stalk only, the agricultural wastes of husk and so on just have more than 700,000,000 ton every year, amount to more than 300,000,000 ton of standard coal, therefore promote the use of biomass fuel and boiler plant, realize clean burning and energy-saving combustion, not only can lower production cost, increase economic efficiency, what positive effect was more arranged is the pressure that can extenuate oil demand.
Because the difference of biomass fuel volatilization washiness and existing burner combustion system shows biomass fuel ignition condition instability, startup is slow, causes burning slow insufficient with burning, and heat exchange efficiency is not high yet.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, the biomass fuel hot-water boiler that provide that a kind of ignition condition is good, start-up time is short, can realize fully burning, heat exchange efficiency is high.The technical solution adopted in the present invention is: the high-temperature flue that the present invention includes burner hearth, chimney arch, fire door, fire grate, feed hopper and be communicated with described burner hearth, the tortuous circuitous hot water heating tube that is placed with in described high-temperature flue, in described burner hearth, be provided with the fixed step fire grate angled between feed hopper and the fire grate with horizontal plane, the bottom of described fixed step fire grate extends to the top of described fire grate, the upper end of described fixed step fire grate is provided with expeller movable about level, in the bottom of described fixed step fire grate air blast is housed; The inner vertical direction relative with described fixed step fire grate of described burner hearth is provided with one section arc chimney arch.
Described fixed step fire grate becomes 40 °～45 ° angles with horizontal plane.
Bottom at described fire grate is provided with ashpit.
The invention has the beneficial effects as follows: because the hot water heating tube is tortuous circuitous being arranged in the high-temperature flue, thermocontact area is big, and heat exchanger time is long, the heat exchange efficiency height; In described burner hearth, be provided with the fixed step fire grate angled with horizontal plane, the lower end of described fixed step fire grate extends to the top of described fire grate, the upper end of described fixed step fire grate is provided with expeller movable about level, in the bottom of described fixed step fire grate air blast is housed; The inner vertical direction relative with described fixed step fire grate of described burner hearth is provided with one section arc chimney arch, described arc chimney arch with heat reflection near the charging aperture of the upper end of described fixed step fire grate, making herein, temperature rises and lights biomass fuel, biomass fuel is through preheating and progressively burning on described fixed step fire grate, slide to and carry out secondary on the described fire grate and thoroughly burn, the combustion start time that described arc chimney arch makes shortens, and burns more fully more fast.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the high-temperature flue 9 that the present invention includes water heater shell 14, feed hopper 15, burner hearth 1, chimney arch 2, fire door 4, fire grate 3 and be communicated with described burner hearth 1, above described fire grate 3, be provided with described fire door 4, the below is provided with ashpit 5, described chimney arch 2 adopts high-temperature refractory to make, periphery at described burner hearth 1 and high-temperature flue 9 all is with described chimney arch 2, is filled with insulation material 13 in the space between described chimney arch 2 and water heater shell 14, prevents thermal loss; Tortuous making a circulation is placed with hot water heating tube 7 in described high-temperature flue 9, and thermocontact area is big like this, and heat exchanger time is long, the heat exchange efficiency height, and energy loss is little, and the end of described high-temperature flue 9 is communicated with smoke outlet flue 8.
In described burner hearth 1, also be provided with the fixed step fire grate 10 angled with horizontal plane, this angle operated by rotary motion is between 40 °～45 °, the bottom of described fixed step fire grate 10 extends to the top of described fire grate 3, the upper end of described fixed step fire grate 10 is provided with expeller 12 movable about level, in the bottom of described fixed step fire grate 10 air blast 6 is housed; Described burner hearth 1 inner and described fixed step fire grate 10 relative vertical directions are provided with one section arc chimney arch 11, biomass fuel is after igniting in described fire door 4 places, heat reflection effect through arc chimney arch 11, described fixed step fire grate 10 upper end charging aperture temperature are risen, to shift onto from the biomass fuel that feed hopper 15 gets off on the described fixed step fire grate 10 through expeller 12 again, under air blast 6 effect biomass fuel rapid fire burns and progressively burning in described fixed step fire grate 10 landings, it is very abundant to burn, shorten the combustion start time of water heater greatly, improved efficient.
