摘要： A gas-fired steam-injection boiler has a flue and a water supply pipeline. The flue is provided with a radiation section and a convection section. The water supply pipeline has, in the flue gas flow direction, a first pipe section located at an upstream portion of the convection section, a second pipe section is located at a downstream portion of the convection section, and a third pipe section arranged between the first pipe section and the second pipe section. In a water flow direction of the water supply pipeline, the second pipe section, the first pipe section and the third pipe section are arranged in sequence. By using a flue gas condenser, the temperature of flue gas can be further reduced, and the latent heat of vaporization of steam in the flue gas is absorbed to form condensate water.

摘要： A steam generator for converting a fluid to steam includes a combustion chamber for receiving a combustion fuel into the combustion chamber. A steam chamber surrounds and is heated by the combustion chamber to a temperature exceeding a vaporization temperature of the fluid. A heat exchanging chamber surrounds and is heated by residual heat of the steam chamber. A preheating coil is disposed within the heat exchanging chamber and has a fluid inlet for receiving the fluid under pressure into the preheating coil for preheating the fluid within the heat exchanging chamber. An injector communicates with the preheating coil and the steam chamber for injecting a controlled flow of the preheated fluid under pressure into the steam chamber where it flashes to steam and is super-heated to the temperature of the steam chamber. A steam outlet conveys the super-heated steam externally of the steam generator.

摘要： An integrated comprehensive adjustment method for a pulverized coal boiler based on high-temperature corrosion prevention and control of water wall is provided. The method includes: during shutdown period of the boiler, mounting reducing atmosphere sampling pipe on a water-cooled wall region; carrying out a diagnostic test on the boiler; carrying out an optimization and adjustment test of a boiler pulverizing system; carrying out a single-factor adjustment test of boiler-related parameters; determining degrees of influence of different parameters on water wall reducing atmosphere, thermal efficiency of the boiler and NOx concentration at a denitration inlet; carrying out an optimization test of ammonia spraying of a denitration system; carrying out a maximum safe denitration efficiency test; and finding a balance point among the water wall reducing atmosphere, the thermal efficiency of the boiler and the NOx concentration at the denitration inlet.

摘要： Modern thermal power plants based on classical thermodynamic power cycles suffer from an upper bound efficiency restriction imposed by the Carnot principle. This disclosure teaches how to break away from the classical thermodynamics paradigm in configuring a thermal power plant so that its efficiency will not be restricted by the Carnot principle. The power generation system described herein makes a path for the next generation of low-to-moderate temperature thermal power plants to run at significantly higher efficiencies powered by renewable energy. This disclosure also reveals novel high-performance power schemes with integrated fuel cell technology, driven by a variety of fuels such as hydrogen, ammonia, syngas, methane and natural gas, leading toward low-to-zero emission power generation for the future.

摘要： A sodium-chlorine generator generates electricity. Chlorine gas is combined with sodium metal in a boiler. The reaction is exothermic and generates sodium chloride as a biproduct. The heat can be used to boil water to generate steam. The steam generated can be used to turn a turbine, which produces electricity. The reactor can use a heat exchanger to connect a boiler that is separated from reactor. The rate and output of the reaction can be changed by pressurizing the chlorine gas with the reactor and by preheating the sodium before the reaction. The sodium chloride can be recycled to generate sodium metal and chlorine gas for a subsequent use.

摘要： A method for improving effectiveness of a steam generator system includes providing a steam generator system including a steam generator vessel, an air supply system and an air preheater. The air supply system is in communication with the steam generator vessel through the air preheater and the steam generator vessel is in communication with the air preheater. The air supply system provides a first amount of air to the air preheater. At least a portion of the first amount of air is provided to the steam generator vessel. A flue gas mixture is discharged from the steam generator vessel. At least a portion of the flue gas mixture flows into the air preheater. SO3 in the flue gas mixture is mitigated before the flue gas mixture enters the air preheater.

摘要： Methods and systems for steam production are provided. Methods include providing feedwater having an electrical conductivity of less than 200 μS/cm to an electrode boiler, and converting the feedwater to saturated steam by the electrode boiler. The saturated steam is provided as a first fluid to a heat exchange component. Water having an electrical conductivity of more than 200 μS/cm is provided to the heat exchange component as a second fluid, where the second fluid is heated through indirect thermal transfer with the saturated steam to generate wet steam. The saturated steam is at least partially condensed in the heat exchange component through the indirect thermal transfer with the second fluid. At least a portion of the thus obtained condensed fluid is fed back to the electrode boiler for use as part of the low-conductivity water to generate said saturated steam.

摘要： A multi-fuel microgrid class generator system includes a heat regenerative steam engine that provides a versatile power source having a clean burn using liquid fuel or biomass for generating electricity. The generator system is also capable of using wind energy and/or solar energy that is converted to heat and stored in a thermal storage unit using a heat exchange medium, such as carbon/graphite. The heat regenerative steam engine uses these various power sources to generate up to 1 megawatt of clean and cost-effective electricity.
