Abstract

The invention provides an oil burner with high viscosity, relating to a burner, aiming at solving the problem that the fuel injector on the current burner generally adopts mechanical atomization type and spinning cup type and steam jet type, the flame size of the burner is great and can not be used in the offshore platform steam injection boiler. Fuel oil enters a steam through hole through a second fuel hole, a fuel chamber, a first through hole, a second circular groove, a third circular groove, a first tangential groove, a center hole via a fuel pipe, and simultaneously, the atomizing medium enters the inner cavity of the compression nut through a second atomizing medium hole and the steam cavity via the atomizing medium pipe, then enters the steam through hole via a second tangential groove and a fifth circular groove; the atomizing medium and the fuel mix in the steam through hole and enter the conical hole to obtain primary atomization under the action of the rotational centrifugal force; and the mixed oil is impacted violently by the wind from the tangential air door and the axial air door to obtain the secondary atomization. The invention is applied to the offshore platform steam injection boiler.

Description

technical field [0001] The invention relates to a burner. Background technique [0002] In recent years, a large amount of high-viscosity heavy oil has been found in several oilfields in my country's sea area for exploitation. Offshore oilfield development requires steam injection boilers, which inject high-pressure steam into underground oil layers to provide heat sources for thermal recovery. The fuel for steam injection boilers must use high-viscosity heavy oil from the oilfield. Steam injection boilers on offshore platforms are different from land-based equipment. The weight and size restrictions on steam injection boilers on offshore platforms are particularly strict. Therefore, it is required that the configured burner can achieve small flame size and stable and complete combustion to meet the requirements of the furnace of the boiler. [0003] The oil burner is mainly composed of two parts: the fuel injector and the air regulator. Existing fuel injectors generally a...
