In order to increase the output power of the steam turbine, it is necessary to increase the steam production of the high-pressure boiler and increase the temperature and pressure of the steam. For the high-pressure boiler, there are the following disadvantages: 1. High energy consumption, high-quality coal must be burned to provide sufficient heat energy; 2. The higher the pressure, the stricter the selection of materials, the higher the technical requirements and cost of manufacturing high-pressure boilers; 3. The high-pressure boilers are used continuously, and the pipelines in the furnace are vulnerable and difficult to repair; 4. The high-temperature and high-pressure steam transportation The pipeline is long, and there are some difficulties in the maintenance of the pipeline
For this reason, I once developed a kind of steam pressure only need 10-60kg, safe and reliable, energy-conservation and environmental protection, the high-pressure pulse jet machine of the special steam turbine that can burn low-quality coal or inferior coal, (patent application number: 200510120607.4), but This jet cannot be used for any steam turbine, but only for the energy-concentrated pulse steam turbine developed by me.

Embodiment Construction
[0009] Specific embodiments of the present invention will be further described below in conjunction with accompanying drawing:
[0010] Accompanying drawing 1 is the schematic diagram of the transverse section structure of the concentrated pulse steam turbine. The energy-concentrating pulse steam turbine is composed of a casing 1, a stator 4, a rotor main shaft 8, a rotor blade 7, an exhaust gas recovery port 9, a steam injection port 10, and a base foot 11. It is characterized in that the outer circumference of the cylindrical casing 1 has Rib sound-absorbing layer 12, the reinforcing rib sound-absorbing layer is welded by longitudinal and horizontal iron sheets or castings wrapped around the entire casing, mainly to enhance the impact resistance of the casing, and at the same time can be filled between the longitudinal and horizontal iron sheets Expanded perlite powder for high temperature, heat insulation and sound absorption. There is a stator 4 inside the casing, and the...

The invention relates to an energy-collection impulse turbine, which is formed by a frame, a stator, a rotor main axle, a rotor blade, a waste gas recycle open, and a steam ejector, wherein it is characterized in that: the cylinder frame is mounted with strengthen bar sound-absorption layer; the stator is mounted with recoil baffle plate and bleed baffle plate; the hollow main axle is uniformly symmetry mounted T-shaped rotor blade; each group of blades form one independent system; several systems can be serially connected on the main axle. The invention has lower demand on the steam pressure, as only 10-60kg, and it can burn the low-quality coal as 2000-4000 calorie; and it can improve the safety factor of high-pressure boiler. The invention can be matched with high-pressure impulse ejector; compared with constant-current compression steam turbine, it can improve 25-50% power efficiency.
Description
Technical field: [0001] The invention relates to a mechanical engineering steam turbine, in particular to an energy-gathering pulse steam turbine used in conjunction with a high-pressure pulse jet. Background technique: [0002] At present, the rotation of steam turbine blades depends on the high-temperature and high-pressure steam generated by the high-pressure boiler in the form of constant flow injection from multiple injection ports to drive the blades of the steam turbine to perform work. In order to increase the output power of the steam turbine, it is necessary to increase the steam production of the high-pressure boiler and increase the temperature and pressure of the steam. For the high-pressure boiler, there are the following disadvantages: 1. High energy consumption, high-quality coal must be burned to provide sufficient heat energy; 2. The higher the pressure, the stricter the selection of materials, the higher the technical requirements and cost of manufacturing...
