Embodiment 1

[0017] Embodiment 1: The structure of a novel annular combustion chamber fuel gas steam boiler is as follows figure 1 as shown, figure 2 is the furnace structure diagram, image 3 It is the internal structure diagram of its furnace. The pot shell is arranged upright, four burners 2 are arranged in the same direction along the tangent line of the furnace outside the pot shell, and the furnace is placed in the center of the pot shell. The upper cylinder 5 of the pot shell has an outlet that communicates with the outside of the pot shell and the flue gas discharge pipe 1 in the furnace. There are 4 inlets of pipelines 8 communicating with the outside of the pot shell and the combustion chamber in the furnace gall on the bottom cylinder 4 of the pot shell. The flame injection pipe of the burner 2 is inserted into the combustion chamber through the pipeline 8 connecting the outside of the pot shell and the combustion chamber in the furnace. The pipe 8 connecting the outside of...

Embodiment 2

[0019] Embodiment 2: The structure of the new type annular combustion chamber fuel gas hot water boiler is as follows Figure 4 As shown, only one burner is configured due to the small heating power. The water inlet pipe 16 of the hot water boiler is arranged on the top of the pot shell, the water outlet pipe is arranged on the annular combustion chamber, the water outlet pipe leads into the annular hot water tank 15 outside the upper cylinder of the pot shell, and a hot water valve is installed on the hot water tank 15 .

[0020] The working process of embodiment 2 is: the water inlet pipe 16 of the hot water boiler connects the tap water pipe and connects tap water, and the burner ignites and burns. Water temperature just can open the hot water valve on the hot water tank 15 and get hot water when water temperature reaches prescribed temperature. The tap water pipe automatically replenishes water.

Abstract

The novel annular combustion chamber oil-fired gas boiler provided by the invention has a shell furnace and a water pipe. A plurality of burners are arranged around the outside of the pot shell, and the furnace is arranged in the center of the pot shell. The annular combustion chamber is located in the lower part of the furnace, and the water pipe is located in the upper part of the furnace. The annular combustion chamber is communicated with the upper part of the furnace, and constitutes a flue gas flow channel for combustion and heat exchange. The space between the furnace gallbladder and the boiler shell and the space in the water pipe constitute an upward channel for water evaporation. The overall structure of the boiler is compact, the geometry is simple, the volume is small, the strength is high, the heat exchange is fast and sufficient, and the thermal stress of the furnace is uniform. It gives full play to the advantages of oil-fired gas boilers without solid waste discharge, and basically meets the requirements of quick installation, modularization and overall assembly of medium and large oil-fired gas boilers. It will end the history of oil-fired gas boilers borrowing the structure of coal-fired boilers. It is a boiler suitable for oil and gas characteristics.

Description

technical field [0001] The invention relates to a boiler, in particular to a novel annular combustion chamber fuel gas boiler. Background technique [0002] China is a big importer of energy, especially the import and consumption of natural gas will experience rapid growth. Many coal-fired boilers cause serious environmental pollution, which also prompts China to develop coal liquefaction and gasification to realize the clean utilization of coal. Therefore, fuel gas boiler technology is the key to realize this transformation of energy consumption structure. [0003] At present, most of the widely used oil-fired gas boilers are small and medium-sized shell-type fire-tube boilers. Shell-type fire-tube boilers cannot meet the requirements of medium and large oil-fired gas-fired boilers. The industry generally believes that the development direction of medium and large fuel gas boilers is water tube boilers. Although there are still a small number of water-tube oil-fired gas...
