Abstract
The utility model discloses an internal heat transferring structure of a coal-fired molten salt furnace. The internal heat transferring structure of the coal-fired molten salt furnace comprises a plurality of radiation section furnace tubes (1) and a plurality of convection section furnace tubes (2), one end of each radiation section furnace tube (1) is communicated with a first heat collecting tube (3), and the other end of each radiation section furnace tube (1) is communicated with a second heat collecting tube (4). Each convection section furnace tube (2) is in the shape of a round barrel which spirals upward, one end of each convection section furnace tube (2) is communicated with the first heat collecting tube (3), and the other end of each convection section furnace tube (2) is communicated with the second heat collecting tube (4). The number of the convection section furnace tubes (2) which is in the shape of the round barrel is more than three, and the convection section furnace tubes (2) are arranged coaxially. The internal heat transferring structure of the coal-fired molten salt furnace is simple in structure and convenient to manufacture, and is not limited by transportation conditions. By means of the internal heat transferring structure of the coal-fired molten salt furnace, output power of the coal-fired molten salt furnace is greatly improved, the output power generated by the coal-fired molten salt furnace can reach up to 30 million kilocalorie per hour, and the demands of large coal-fired molten salt furnace with high output power in China can be well met.
Description
Technical field
The utility model relates to a kind of coal-fired molten salt furnace, particularly relates to the furnace heat transfer structure of coal-fired molten salt furnace.
Background technology
The furnace heat transfer structure of existing coal-fired molten salt furnace is comprised of some radiant coils and heating tube in section of convection chamber, and the two ends of described every radiant coil are connected with the first thermal-collecting tube, the second thermal-collecting tube respectively, and described heating tube in section of convection chamber is made of the tube bank of snake shape.The furnace heat transfer structure of this coal-fired molten salt furnace consists of because heating tube in section of convection chamber is restrained by the snake shape, thereby has the less defective of molten salt furnace power output, can't satisfy China to the demand of the large-scale molten salt furnace of high-output power.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of power output that can improve molten salt furnace, thereby can satisfy China to the furnace heat transfer structure of the coal-fired molten salt furnace of the large-scale molten salt furnace demand of high-output power.
For solving the problems of the technologies described above, the utility model adopts a kind of like this furnace heat transfer structure of coal-fired molten salt furnace, formed by some radiant coils and some heatings tube in section of convection chamber, the two ends of described every radiant coil are connected with the first thermal-collecting tube, the second thermal-collecting tube respectively, described every heating tube in section of convection chamber all is the barrel-shaped structure on the screw, and the two ends of described every heating tube in section of convection chamber are connected with described the first thermal-collecting tube, the second thermal-collecting tube respectively.
In the utility model, the described heating tube in section of convection chamber that is barrel-shaped structure is preferably more than three, and these heating tube in section of convection chamber coaxial lines are settled.
Every heating tube in section of convection chamber of the present utility model is the metal circular tube of hollow.
After adopting said structure, because every heating tube in section of convection chamber of the present utility model all is the barrel-shaped structure on the screw, in the utility model, described heating tube in section of convection chamber is preferably more than three, and these heating tube in section of convection chamber coaxial lines are settled, thereby this heat transfer structure increased the power output of molten salt furnace greatly, make the power output of molten salt furnace can expand to 3,000 ten thousand kilocalories/hour, thereby satisfied the demand of China to the large-scale molten salt furnace of high-output power.
