Description

Rotary mechanical atomizing oil burner

Technical field

The utility model relates to combustion apparatus-burner that chamber combustion type boiler is used, and specifically is a kind of rotary mechanical atomizing oil burner that is applicable to gas fired-boiler.

Background technology

The flame-out port that advances burner and burner of existing chamber combustion type boiler directly is tightly connected, boiler is with the positive-pressure type closed operation, owing to be in airless state in the boiler body, burner sprays into concentration one height of fuel gas/coal dust in boiler body, will when lighting a fire, burner blast, therefore, just stipulate in the boiler design standard: " burner that chamber combustion type boiler is equipped with should adopt has the burner that the electromechanical integration of function is controlled in multiple safeguard protection automatically ", so that accurately control the spray volume of the fuel gas/coal dust of burner, and the duration of ignition, avoid origination point fiery fried; And present domestic chamber combustion type boiler all adopts the import burner, and cost is high, because burner itself is a precise electronic product, in case break down, maintenance is difficult for, and controls personnel and must possess certain know-how, deviation is arranged slightly, just can the people explode for causing igniting.

Summary of the invention

The utility model is that the import burner of avoiding hidden peril of explosion to adopt causes production cost height, later stage to be moved controlling the demanding problem of peopleware in order to solve existing chamber combustion type boiler, and a kind of low cost of gas fired-boiler, rotary mechanical atomizing oil burner easy and simple to handle of being applicable to is provided.

The utility model is to adopt following technical scheme to realize: rotary mechanical atomizing oil burner, comprise combustion head and pedestal, combustion head and pedestal are built-in with Gas Pipe respectively, combustion head is provided with blast pipe, the combustion head bottom is fixed together with rotational structure with the pedestal top, the interior Gas Pipe of Gas Pipe in the burner and pedestal is connected with rotatory sealing, and the pivot center of rotational structure overlaps with the rotation of two combustion tubes between combustion head, pedestal.Wherein, the structure in the combustion head is fully to be mixed into purpose with combustion gas and air, and malformation is a lot, do not describe in the specification, and be 02270411.6 the disclosed nozzle arrangements of Chinese patent but can adopt the patent No. at least.

During installation, make the flame-out port of combustion head and boiler body advance burner over against, and separate and be provided with; The blast pipe of combustion head is connected with blower fan, and the Gas Pipe in the pedestal is connected with gas pipeline by burnt gas valve; Before the igniting, open blower fan and burnt gas valve, combustion head is reversed by the staff, make the flame-out port of combustion head depart from the burner that advances on the furnace body that boils, light a fire by the staff again, after the igniting, combustion head is resetted, and what make the flame-out port of combustion head and boiler body advances burner over against getting final product.

But before using rotary mechanical atomizing oil burner described in the utility model, need boiler body is carried out structural modification, so that guarantee that the utility model can use, promptly on the chimney of boiler body, install the pumping and leading-in device that improves the chimney emission ability additional, and before igniting, start, make to be in negative pressure state in the boiler body, the thermal-flame of the flame-out port ejection of burner can carry out heat exchange by advancing in the burner suction boiler body on the boiler body.

According to theory of the present utility model, in chamber combustion type boiler: the coal burner of pulverized-coal fired boiler, oil burning boiler and oil burner also can be rotated the formula structural design.

The utility model is simple and reasonable for structure, and cost is low, uses, controls conveniently, is applicable to gas fired-boiler in the chamber combustion type boiler and metal magnesium reduction furnace etc.
