Description

A kind of solid fuel steam generator

Technical field

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

Background technology

Steam generator is a hot machine that can the kinetic energy in the steam be converted into merit.Pump, locomotive engine and steamer once used steam generator power.Steam generator has play a part basic in the industrial revolution.Today, people also used steam turbine engines to generate electricity.

Yet in real world devices, what steam generator was used is steam; Steam externally does work, and heat is directly arranged to the external world, and what thermal loss was maximum is taken out of by gas exactly; In addition; Steam generator has also lost suitable heat in the exhaust emissions process, so the efficient of steam generator is lower.

The utility model content

The technical problem that the utility model mainly solves provides a kind of solid fuel steam generator, can the utility model can improve the automatization level of steam generator, improves the thermal efficiency.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of solid fuel steam generator is provided.Comprise: steam generator body, the steam (vapor) outlet of steam generator body top, the burner hearth of steam generator body bottom; Igniter in the burner hearth, the feeding-passage of connection burner hearth, the hopper of feeding-passage top; The chimney that connects burner hearth, the slag-drip opening of burner hearth bottom also comprises the high-temperature flame-proof wall that burner hearth is outside; But the base of lower furnace portion and fast pulley connect the water inlet pipe of steam generator body and the valve on the water inlet pipe.

In preferred embodiment of the utility model, an economizer is arranged between said burner hearth and the chimney, the inner water pipe journey serpentine of economizer distributes.

In preferred embodiment of the utility model, there is a temperature sensor said burner hearth inside.

In preferred embodiment of the utility model, an automatically-controlled door is arranged between said feeding-passage and the hopper.

In preferred embodiment of the utility model, said burner hearth inside also comprises a fire grate, and a plurality of apertures are arranged on the fire grate.

In preferred embodiment of the utility model, said steam generator body interior has a liquid level sensor.

The beneficial effect of the utility model is: a kind of solid fuel steam generator of the utility model, an economizer is arranged between its burner hearth and chimney, and can improve the utilization rate of tail gas heat quantity, and then improve the thermal efficiency of steam generator.

Description of drawings

Fig. 1 is the structural representation of a kind of solid fuel steam generator of the utility model;

The mark of each parts is following in the accompanying drawing: 1, hopper, 2, automatically-controlled door, 3, the steam generator body, 4, feeding-passage, 5, temperature sensor; 6, burner hearth, 7, the high-temperature flame-proof wall, 8, slag-drip opening, 9, base, 10, fast pulley; 11, igniter, 12, water inlet pipe, 13, valve, 14, economizer; 15, chimney, 16, liquid level sensor, 17, steam (vapor) outlet, 18, fire grate.

The specific embodiment

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

As shown in Figure 1, a kind of solid fuel steam generator comprises: steam generator body, the steam (vapor) outlet of steam generator body top; Igniter in the burner hearth of steam generator body bottom, burner hearth, the feeding-passage of connection burner hearth; The hopper of feeding-passage top, the chimney of connection burner hearth, the slag-drip opening of burner hearth bottom; Also comprise the high-temperature flame-proof wall that burner hearth is outside, but the base of lower furnace portion and fast pulley connect the water inlet pipe of steam generator body and the valve on the water inlet pipe.

Further, an economizer is arranged between said burner hearth and the chimney, the water of the water inlet pipe economizer of flowing through earlier enters into the steam generator body again, has improved the temperature of water, and the inner water pipe journey serpentine of economizer distributes, thereby has increased contact area.

Further, a temperature sensor is arranged in the said burner hearth, when the fuel combustion in the burner hearth finished soon, the temperature that temperature sensor detects this moment had significantly reduction.

Further, an automatically-controlled door is arranged between said feeding-passage and the hopper, when the temperature sensor in the burner hearth detected the temperature reduction, automatically-controlled door was opened, and added fuel to burner hearth.

Further, said burner hearth inside also comprises a fire grate, and fuel burns on fire grate, and the residue of generation or ashes are fallen into the fire grate below from the aperture on the fire grate, and discharges burner hearth from breast hole.

Further, said steam generator body interior has a liquid level sensor, and when the water level in detecting the steam generator body was lower than sensor, the valve open of water inlet pipe supplied water for the steam generator body.

The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; 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 utility model.
