3. The application range is wide:
the boiler is not only suitable for burning coal, but also particularly suitable for burning biomass fuel, and has a very wide application range.
4. Simple structure, low in production cost:
the utility model has simple structure, needs no economizer and air preheater, can be directly transformed by the original horizontal shell-and-pan boiler, and has lower production cost; and because the low-temperature boiler shell of the utility model is not heated by the heat radiation of the flue gas, the thickness of the low-temperature boiler shell can be thinned, thereby further reducing the production cost and ensuring that the boiler is easy to popularize and use.
The technical features of the high-efficiency horizontal shell-type boiler of the present invention will be further described with reference to the accompanying drawings and examples.

Detailed Description
The first embodiment is as follows:
fig. 1-4 disclose a high-efficiency horizontal shell-type boiler, which comprises a hearth, a shell and a water tank 9, wherein the shell is composed of a high-temperature shell 2 and a low-temperature shell 8, the high-temperature shell 2 and the low-temperature shell 8 are internally provided with communicated smoke pipes 5, each shell is respectively provided with a safety valve 4, a water inlet 6 and a steam outlet 3, and each water inlet 6 is provided with a check valve 7; the high-temperature pot shell 2 is arranged above the hearth 1, the low-temperature pot shell 8 is arranged outside the hearth 1 and communicated with the water tank 9, and the high-temperature pot shell 2 and the low-temperature pot shell 8 are connected in series through a water pipe communicated with a water inlet of the high-temperature pot shell and a water vapor outlet of the low-temperature pot shell. The water tank 9 is a stepped progressive water tank formed by communicating three independent water containers, the three independent water containers are respectively a first-stage water container 901, a second-stage water container 902 and a last-stage water container 903 which are horizontally arranged together, communicated smoke tubes 5 are arranged in the independent water containers at all stages, smoke in the smoke tubes of the last-stage water container 903 is communicated with the smoke tubes of the low-temperature boiler shell, and the smoke of the smoke tubes of the first-stage water container 901 is discharged from a chimney through a draught fan; a water outlet and a water inlet connected with a ball float valve 13 are respectively arranged on each stage of independent water container, wherein a water inlet 10 of the first stage water container 901 is arranged at the top of the first stage water container 901 and is connected with a natural water supply pipe; the water outlet 11 of the last stage water container is communicated with the water inlet 6 of the low-temperature boiler shell 8 through a water pipe with a water pump 12.
The working principle of the high-efficiency horizontal shell-and-pan boiler of the embodiment is as follows:
high-temperature flue gas discharged from a hearth enters a low-temperature boiler shell for heat exchange through a smoke pipe after the high-temperature boiler shell and water exchange, then enters a water tank to flow in sequence according to the sequence of a last-stage water container 903, a second-stage water container 902 and a first-stage water container 901, and is finally discharged from a chimney through a draught fan (the arrow direction shown in figure 1 is the flue gas flow direction), so that the temperature of the flue gas is greatly reduced after the flue gas is subjected to multi-stage heat exchange, and the thermal efficiency of the flue gas is very high. Water and steam can only flow from the low-temperature boiler shell to the high-temperature boiler shell, and water is subjected to heat radiation of the hearth and heat exchange of high-temperature flue gas in the high-temperature boiler shell, so that the temperature of water can quickly rise, and then the water and the steam are discharged from a steam outlet of a high-temperature area.
