specific Embodiment approach 1

[0008] Embodiment 1: Combining Figure 1-Figure 7 It is explained that the boiler of this embodiment includes a furnace body 14 and a furnace door 1; the boiler also includes a biogas burner 2, a biogas gas transmission pipe 3, an air baffle 6, a heat exchanger 11, a biogas gas transmission pipe valve 16 and a primary air pipe 19; The furnace body 14 is composed of a flue 14-1, a furnace chamber 14-2 and a lower furnace cavity 14-3 in order from top to bottom, and the furnace chamber 14-2 and the lower furnace chamber 14-3 are separated by an air partition 6 Open, the side walls of the flue 14-1 and the furnace 14-2 are water jackets 10 with interlayers, the furnace door is arranged on the side wall of the furnace body 14 and is located in the lower furnace cavity 14-3, and the furnace door 1 is arranged at At the door of the furnace, the air baffle 6 is provided with a fixing hole, the lower end of the biogas burner 2 is arranged on the bottom end surface in the lower furnace...

specific Embodiment approach 2

[0009] Specific implementation mode 2: Combining Figure 1-Figure 4 It is explained that the multi-layer finned tubes 11-1 of the present embodiment are arranged in parallel and inclined, and the included angle α between each layer of finned tubes 11-1 and the horizontal direction is 5°˜10°. The invention draws on the boiler design principle in the design of the heat exchanger, and the finned tubes of the heat exchanger are arranged inclined (5°~10°), which is conducive to the circulation of water in the tubes, and the tubes are provided with fins to greatly increase the heat exchange area and improve the heat utilization. Others are the same as the first embodiment.

specific Embodiment approach 3

[0010] Specific implementation three: combination figure 1 and figure 2 It is explained that the adjacent two layers of the multi-layer finned tubes 11-1 of this embodiment are arranged in a staggered arrangement (for example, each finned tube of the upper layer of finned tubes is located between the adjacent two finned tubes corresponding to the lower layer of finned tubes. space between). With this arrangement, the heat exchange coefficient can be increased, and the heat exchange between the flue gas and the warm water in the finned tubes can be sufficiently achieved. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a methane-burning heating boiler and relates to a heating boiler, aiming at solving the problem that the traditional methane boiler can not be used for indoor heating in north rural areas. A boiler body consists of a flue, a hearth and a lower boiler chamber in sequence from top to bottom, the hearth and the lower boiler chamber are separated by an air partition, the side walls of the hearth and the hearth are provided with water jackets with an interlayer, the lower end of a methane burner is arranged on a bottom end surface inside the lower boiler chamber, the upper end of the methane burner passes through the air partition and is arranged in the hearth, the methane burner is provided with an air inlet pipe and a secondary air inlet which are communicated with each other, a methane supply pipe is communicated with the inlet pipe of the methane burner, a heating water inlet communicated with the water jackets is arranged on the outer wall of the hearth, at least one heating water outlet communicated with the water jackets is arranged on the water wall of the flue, a heat exchanger is arranged in the hearth and consists of a multi-layer finned tube, the twoends of the multi-layer finned tube are communicated with the water jackets, and the methane supply pipe is provided with a methane supply pipe valve. The invention can be used for the indoor heatingin north rural areas.

Description

technical field [0001] The invention relates to a heating boiler. Background technique [0002] Biogas has been widely used as an environmentally friendly fuel in rural areas due to its advantages of local materials, high quality and low price. At present, the waste fermentation biogas project will still be a practical and effective method for my country's renewable energy utilization and environmental protection. [0003] In order to facilitate the utilization of biogas in suburban and rural areas, as well as industrial and agricultural production units and households that need steam, the invention patent application with publication number CN 101042232A and published on April 30, 2007 discloses a biogas boiler. The biogas, which is locally sourced, cheap, and environmentally friendly, can be used as fuel, as well as natural gas, liquefied gas or coal gas used in urban and rural areas. Although the biogas boiler has the advantage of compact structure, it is a steam boiler....
