Problems solved by technology

Among them, the gas steam generator is a kind with a wide range of applications. Domestically produced gas steam generators are very different, and the auxiliary equipment can not meet the requirements of use.
In the manufacturing process of gas steam generators, due to different manufacturers, there are too many factors of raw materials, product structure, auxiliary equipment configuration and human defects in the manufacturing process. The water content is large, and the water capacity of the manufactured gas steam generator exceeds the standard; (2) Due to frequent water supply and low water temperature, the steam production is interrupted during use; (3) The existing steam generator has a relatively simple structure, which not only affects the generation of gas steam The operation of the gas steam generator, and it is easy to cause water shortage and pipe burst, which seriously affects the normal use of the gas steam generator

Embodiment 1

[0032] This embodiment provides a steam generator, which includes a tank body 1, a burner 2 and a steel frame arranged in the tank body 1, and the opposite sides of the tank body 1 are respectively provided with air inlets 3 communicating with the burner and the chimney mouth 4, an economizer 5 communicating with the chimney mouth 4 is arranged in the tank body 1 on the side of the chimney mouth 4, and a preheater 6 is arranged in the tank body 1 on the side of the air inlet; The economizer 5 is provided with a water inlet 51 and a water outlet 52, the preheater 6 is provided with a preheating pipe 61, the water outlet 52 of the economizer 5 communicates with the preheating pipe 61, and the tank body 1 is provided with a main steam valve 7 communicating with the preheating pipe 61. Water at normal temperature enters the economizer 5 through the water inlet 51 on the economizer 5, and then enters the preheater 6 through the water outlet 52. During the whole process, since one s...

Embodiment 2

[0034]Embodiment 2 is further defined on the basis of Embodiment 1: a smoke-folding wall 8 is provided between the preheater 6 and the economizer 5, and a smoke-folding wall 8 is reserved between the top of the smoke-folding wall 8 and the top of the tank body 1 There is a flue gas passage, and a smoke folding baffle 81 connected to the preheating pipe 61 is arranged horizontally on the top of the smoke folding wall 8 , and the flue gas in the preheater 6 flows along the flue gas passage. The hot gas used in the preheater by the smoke-folding wall 8 can be blocked by the smoke-folding wall 8 and then flow back into the space of the preheater 6 for heating. Using the function of the smoke-folding baffle 81, the hot gas rises to the bottom of the preheater 6 The upper part enters the economizer 5 through the flue gas channel, which improves the utilization rate of the hot gas, avoids the heat loss caused by the direct entry of the hot gas into the economizer 5, and improves the e...

Embodiment 3

[0036] Embodiment 3 is further defined on the basis of Embodiment 1: the preheater 6 includes two preheating pipes 61, and the two preheating pipes 61 are arranged in an S-shaped curve from bottom to top. The preheating pipes cross each other and are not communicated. The inlet of the lower part of the preheating pipe 61 communicates with the water outlet of the economizer 5 . The steam storage package 62. The hot water in the preheating pipe 61 moves from bottom to top to the steam storage package 62 on the upper part of the preheating tube 61 while being heated. When it is in the steam storage package 62, it has been directly usable steam, and the steam storage package 62 is set There are pressure gauges 63 and safety valves 64 for measuring pressure to avoid potential safety hazards caused by excessive pressure, and a main steam valve for connecting to the outside and using steam is provided.

Abstract

The invention discloses a steam generator and a manufacturing method thereof. The steam generator comprises a tank body, and a steel frame and a combustor which are installed in the tank body. Two opposite sides of the tank body are provided with an air inlet and a chimney port communicated with the combustor. The tank body, positioned at one side of the chimney port, is internally provided with an energy saver communicated with the chimney port. The tank body, positioned at one side of the air inlet, is internally provided with a preheater. The energy saver is provided with a water inlet anda water outlet. The preheater is internally provided with a preheating tube. The water outlet of the energy saver is communicated with the preheating tube. The top of the tank body is provided with amain steam valve communicated with the preheating tube. According to the steam generator and the manufacturing method thereof, the steam generator is stable in operation, not easy to cause phenomena of water shortage and tube explosion, and the steam generator can be conveniently and normally used.

Description

technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to a steam generator and a manufacturing method thereof. Background technique [0002] Existing steam generators are generally divided into five types according to fuel, gas steam generators, fuel oil steam generators, electric heating steam generators, coal-fired steam generators and biomass steam generators. Among them, gas-fired steam generator is a type with a wide range of applications. Domestically-produced gas-fired steam generators are very different, and the matching of auxiliary equipment cannot meet the requirements for use. In the manufacturing process of gas steam generators, due to different manufacturers, there are too many factors of raw materials, product structure, auxiliary equipment configuration and human defects in the manufacturing process. The water content is large, and the water capacity of the manufactured gas steam generator exceeds the sta...
