Liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion

Abstract

The invention relates to a liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion. The liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion comprises a plurality of gasifier heads, an ignition mechanism, a fuel supply system, an air duct, an air valve and a fan. The liquid fuel gasification combustor is electronically controlled and can be started in a one-click mode to operate automatically. In use, the air duct is divided into an intra-furnace air duct part and an extra-furnace air duct part according to the position relationship with a boiler. An air-oil mixing box is embedded in the top surface of the intra-furnace air duct part. The gasifier heads are evenly and fixedly mounted in the air-oil mixing box at intervals. An oil supply pipe is connected to the bottom of each gasifier head. The oil supply pipes are led out through the air duct and connected with the externalfuel supply system. The ignition mechanism is mounted above the air-oil mixing box and located on the side close to the extra-furnace air duct part. According to the liquid fuel gasification combustor suitable for mixed alcohol oil and capable of achieving complete combustion, the multiple gasifier heads are mounted in the air-oil mixing box so that multiple burners can be ignited at the same time; and in addition, fuel oil which is not completely combusted can be stored in the air-oil mixing box so as to be combusted for the next time, so that waste is avoided, and the oil utilization rate of the liquid fuel gasification combustor is far higher than that of common combustors on the market.

Description

Technical field [0001] The invention belongs to the field of burners, and relates to a liquid fuel burner, in particular to a liquid fuel gasification burner that can use mixed alcohol oil and burn 100%. Background technique [0002] The combustion equipment currently being used in China is a copy of the combustion engine model introduced from abroad in the 1960s and 1970s. The overall technical content is low and there are six major defects: [0003] 1. Liquid fuels require high-standard, high-grade and pure fuels to ensure their usability. This fuel has no advantage in market competition due to its high price-performance ratio; [0004] 2. Although the flame temperature of the burner port of the burner is high, the temperature of the injection is lower with the extension of the boiler length and the flame length, and the exit temperature is very different from the flame end temperature, which is not conducive to the thermal efficiency of the boiler internal temperature balance.

AI Technical Summary

Problems solved by technology

[0003] 1. Liquid fuel requires high-standard, high-grade, pure fuel to ensure its usability. This fuel has no advantage in market competition due to its high price and performance-to-price ratio;

[0004] 2. Although the flame temperature of the flame nozzle of the burner is high, the temperature of the injection is low after the flame length of the boiler is extended, and the outlet temperature is greatly different from the temperature of the flame end, which is not conducive to the internal temperature balance of the boiler and the thermal efficiency.

[0005] 3. When the burner uses low-grade fuel, part of the injected fuel quickly falls outside the nozzle and no longer burns, but gradually evaporates and wastes resources in the high-temperature space; the ignition reliability is reduced and unsafe

[0007] 5. The choice of fuel used is limited, and diversified low-cost fuels are rejected and unusable or unsafe to use when sick

The fuel is only atomized but not gasified and burned, which is seriously unfavorable to economic calculation and environmental protection testing.

[0008] 6. Most vertical boilers use old-fashioned burners. The flame erupts horizontally. The length of the flame is limited. The diameter of the boiler is very short. Inefficient and inconvenient

This patent was applied for by the applicant in 2015. The structure of this patent mentions the integration of multiple burners and the sharing of air boxes, which solves the problem of increasing the heat release area, but the disadvantage is that multiple burners need to be ignited separately. , making it impossible to apply
