An industrial boiler capable of burning multiple fuels

Abstract

This utility model discloses an industrial boiler capable of burning multiple fuels, including a boiler body. A fixing frame is fixedly connected to the surface of the boiler body, and a mixing box is fixedly connected to the top of the fixing frame. Multiple air inlet pipes are fixedly connected to the surface of the mixing box, and the interior of the air inlet pipes is connected to the interior of the mixing box. A partition is provided inside the mixing box, and a circular hole is opened at the center of the partition. An air supply pipe is fixedly connected inside the circular hole. These various types of fuel gases are blown by moving pressure to rotate the mixing fan blades. The rotation of the mixing fan blades mixes these various types of fuel gases to form a mixed fuel gas, which enters the combustion chamber inside the boiler body through the air supply pipe. The mixed fuel gas is ignited by an igniter to burn. This method is more economical and can effectively reduce the consumption of a single fuel gas and prevent the boiler body from shutting down.

Description

Technical Field

[0001] This utility model belongs to the field of boiler technology, and in particular relates to an industrial boiler that can burn multiple fuels. Background Technology

[0002] Industrial boilers, as core heat energy supply equipment in the industrial production field, are widely used in many scenarios such as chemical reaction heating, heat treatment of mechanical manufacturing workpieces, textile printing and dyeing drying, and combined power generation. Their fuel consumption costs account for 30%-50% of the total energy consumption costs of enterprises. The stability of operation and the economy of fuel utilization directly determine the core competitiveness and green production level of enterprises.

[0003] Currently, most mainstream industrial boilers on the market adopt a single fuel compatibility design, meaning they can only be adapted for combustion of one specific type of fuel gas, such as natural gas, liquefied petroleum gas, and blast furnace gas. Fuel supply is highly dependent on a single type. If the market price of that fuel fluctuates, such as natural gas supply shortages leading to price increases in winter, supply chain disruptions, transportation disruptions, or upstream gas shortages, it will directly lead to boiler shutdowns or a surge in enterprise energy costs, seriously affecting production continuity. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an industrial boiler capable of burning multiple fuels. It connects to various types of fuel gases via an inlet pipe. A conical baffle allows these fuel gases to flow into the gas delivery pipe. The moving pressure of these fuel gases drives a mixing fan blade to rotate, mixing them to form a mixed fuel gas mixture. This mixture then enters the combustion chamber inside the boiler body through the gas delivery pipe. An igniter ignites the mixed fuel gas mixture, resulting in better economic utilization, effectively reducing the consumption of a single fuel gas, and preventing boiler shutdowns.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an industrial boiler capable of burning multiple fuels, comprising a boiler body, a fixed frame fixedly connected to the surface of the boiler body, a mixing chamber fixedly connected to the top of the fixed frame, multiple air inlet pipes fixedly connected to the surface of the mixing chamber, the interior of the air inlet pipes communicating with the interior of the mixing chamber, a partition plate provided inside the mixing chamber, a circular hole provided at the center of the partition plate, an air supply pipe fixedly connected to the interior of the circular hole, a combustion chamber provided inside the boiler body, a fixed bracket fixedly connected to the interior of the air supply pipe, a fan blade rotatably connected to one end of the fixed bracket, an igniter provided on the surface of the boiler body, one end of the igniter movably penetrating and extending into the interior of the combustion chamber.

[0006] Furthermore, the partition is cone-shaped.

[0007] Furthermore, the air supply pipe is fixedly inserted through and extends into the interior of the combustion chamber.

[0008] Compared with the prior art, the beneficial effects of this utility model are: The boiler connects to various types of fuel gases via an intake pipe. A conical baffle allows these gases to flow into the gas supply pipe. The pressure from the flowing gases drives the mixing fan blades, which mix the gases to form a fuel mixture. This mixture then enters the combustion chamber inside the boiler body through the gas supply pipe. An igniter then ignites the mixture, resulting in better fuel economy, reduced consumption of single fuel gases, and prevention of boiler shutdowns. Attached Figure Description

[0016] Working principle: The system connects to various types of fuel gases via the intake pipe 4. The conical baffle 5 allows these fuel gases to flow into the air supply pipe 6. The moving pressure of these fuel gases drives the mixing fan blades 7 to rotate. The rotation of the mixing fan blades 7 mixes these fuel gases to form a mixed fuel gas mixture. This mixture then enters the combustion chamber 8 inside the boiler body 1 through the air supply pipe 6. The igniter 9 ignites the mixed fuel gas mixture, resulting in better economic utilization and effectively reducing the consumption of single fuel gases, thus preventing boiler shutdown.
