Problems solved by technology

[0004] However, electric boilers consume high-grade energy, produce relatively low-grade low-pressure steam, and fail to achieve temperature matching and cascade utilization. Although the conversion efficiency can approach 100% efficiency, the irreversible loss is large and the economy is not high. Urgent need to improve utilization efficiency

Abstract

The invention relates to a condensate-water-circulation electric steam boiler energy-saving system and a method, and belongs to the technical field of energy conservation. The system involves heat utilization equipment, a flash evaporator, a preheating energy saver, an electric steam boiler and a jet type pressure mixer; steam condensate generated by the heat utilization equipment is divided intotwo paths, the first path is connected with the flash evaporator through a throttling valve, and the second path communicates with the electric steam boiler through a water pump; the flash evaporatorcommunicates with the preheating energy saver; a condenser capable of dissipating heat is arranged in the preheating energy saver; the electric steam boiler communicates with a power steam port of thejet type pressure mixer; the flash evaporator and the preheating energy saver communicate with an injection steam port of the jet type pressure mixer; and a steam outlet of the jet type pressure mixer is connected with the heat utilization equipment. Under general working conditions, the system can obtain about 6% of energy-saving benefits, a large amount of electric energy can be saved after long-term operation, and economic benefits are remarkable.

Description

technical field [0001] The disclosure belongs to the technical field of energy saving, and in particular relates to an energy saving system and method for an electric steam boiler with condensate circulation. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Due to environmental reasons, small coal-fired and gas-fired boilers are gradually banned and replaced by heat pumps or electric boilers, especially in industrial fields that require steam. Electric steam boilers are the most reliable and convenient equipment. [0004] However, electric boilers consume high-grade energy and produce relatively low-grade low-pressure steam. They do not achieve temperature matching and cascade utilization. Although the conversion efficiency can be close to 100%, the irreversible loss is large and the economy is not high. There is an urgent need to improve utilizat...
