Novel efficient energy-saving superheat boiler

Abstract

The invention relates to a novel efficient energy-saving superheat boiler. The novel efficient energy-saving superheat boiler comprises a superheater outlet header, a superheater, a superheater inlet header, a waste heat steam and low-temperature steam input pipe, a saturated steam pipe, a boiler barrel, an ascending pipe, a descending pipe, an evaporator, a hot water pipe, a coal economizer and a boiler water feeding pipe. The superheater outlet header is connected with the sruperheater. The superheater is connected with the superheater inlet header. The superheater inlet header is connected with the waste heat steam and low-temperature steam input pipe and the saturated steam pipe. The saturated steam pipe is connected with the boiler barrel. The boiler barrel is connected with the ascending pipe, the descending pipe and the hot water pipe. The ascending pipe and the descending pipe are connected with the evaporator. The hot water pipe is connected with the coal economizer. The coal economizer is connected with the water feeding pipe. The novel efficient energy-saving superheat boiler has the beneficial effects that efficient heating and superheating of waste heat steam and low-temperature steam are achieved, latent heat of vaporization of water is avoided and reduced, and the problem of superheating of a large amount of saturated steam in the production process of the steel industry is solved.

Description

technical field [0001] The invention relates to energy saving and emission reduction technology and equipment, in particular to a new type of high-efficiency energy-saving overheating boiler. technical background [0002] Usually, a superheater is installed in the boiler, and its main function is to heat and superheat the saturated steam produced by the boiler itself. [0003] At present, the amount of steam produced by waste heat recovery and utilization is particularly large, but due to the limited temperature of most waste heat sources, the temperature of the waste heat steam generated is relatively low, resulting in low power and power generation rate of waste heat steam. [0004] How to increase the temperature of waste heat steam, increase the power and power generation rate per unit of waste heat steam, and improve the thermal efficiency and investment efficiency of waste heat power and power generation projects are urgent problems to be solved in current energy-savin...
