Dual-output atomizer

Abstract

The invention relates to a dual-output atomizer, which comprises a body, a splitter vane, an atomizer A and an atomizer B, wherein the splitter vane, the atomizer A and the atomizer B are sequentially propped against the body and are sheathed and fixed by an end cover; the body is cylindrical, and a channel A and a channel B are formed at the center; one side of the splitter vane is propped against the body, for corresponding to the channel A and the channel B of the body, an inner circle of through holes and an outer circle of through holes are formed on the splitter vane; an annular oil balancing groove and a spin chamber, as well as a tangential groove around the spin chamber are formed on the side surface of the atomizer A, which is propped against the splitter vane; third oil inlet holes are arranged on the outer side of the annular oil balancing groove along the circumference of the atomizer A; a spin chamber corresponding to the spin chamber of the atomizer A is arranged on the side surface of the atomizer B, which is propped against the atomizer A, and the tangential groove is further arranged around the spin chambers; and a horn-shaped spout, which is communicated with the spin chamber and inwards concave, is arranged on the other side surface of the atomizer B. The two atomizers using a same set of program and mechanism used for controlling advance and retreat can simultaneously perform advance and retreat, and a variety of energy can be accurately and timely supplied under complex and emergency working conditions, thereby meeting complex combustion requirements of energy supply under the different working conditions.

Description

Technical field [0001] The invention relates to combustor technology, in particular to a dual-output atomizer suitable for boilers using oil burners in power stations, petrochemicals, metallurgy, etc., by controlling different fuel flow rates to meet different fuel flow rates under various load sections. Background technique [0002] The oil burners used in oil-fired boilers in the power station, petrochemical, metallurgical and other industries have always been traditional, single-output atomizers. In each stage of boiler operation, in different load sections, different energy supplies are required. Generally, the required energy can be achieved through the following two methods: [0003] 1. Replace the atomizer of the burner to achieve the required energy supply; [0004] 2. Increase or decrease the number of burners in operation to achieve the required energy supply. [0005] Both methods have certain disadvantages: [0006] 1. To replace the atomizer, the burner must be shut down...

AI Technical Summary

Problems solved by technology

In a program-controlled control environment, if the burner cannot be put into operation correctly or any one of the programs (actions) fails, the next program will not be able to proceed

In this way, even if the burner is put into operation in time, it cannot provide timely energy supply.
