Description

Technical Field

[0001] This utility model relates to the field of semi-coke boiler technology, specifically to a high-efficiency semi-coke boiler that is not prone to coking. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. Semi-coke is made by burning fine coal lumps. As a new type of carbon material, it is characterized by its high fixed carbon content, high resistivity, high chemical activity, low ash content, low aluminum content, low sulfur content, and low phosphorus content.

[0003] Currently, there are many types of semi-coke boilers. For example, Chinese Patent 201920762748.3 proposes a semi-coke boiler that is easy to clean. By setting up an automatic feeding device, it can effectively realize the automated transfer of materials, saving manpower and material resources, greatly improving work efficiency and saving costs. By setting up a connecting device, the ash produced by the combustion of semi-coke boiler can be effectively discharged. The box door can be flipped up, and the ash can be discharged from the box door through the conveyor belt. The operation is simple.

[0004] However, traditional semi-coke boilers still suffer from large heat loss and coking during combustion, which makes cleaning the boiler interior troublesome. Therefore, a high-efficiency semi-coke boiler that is less prone to coking is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-efficiency semi-coke boiler that is less prone to coking. It has advantages such as improved heat energy conversion, increased thermal efficiency, and improved combustion plate that prevents coking. It solves the problems of large heat loss and coking during combustion in traditional semi-coke boilers, which lead to troublesome internal cleaning of the boiler.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency semi-coke boiler that is not prone to coking, comprising a base, a heat recovery assembly and a combustion assembly fixedly installed on the top of the base, a top plate fixedly installed on the top of the heat recovery assembly and the combustion assembly, a conveying cylinder fixedly installed on the top of the top plate, an induced draft fan fixedly installed on the top of the conveying cylinder, a chimney fixedly installed at the output end of the induced draft fan, a fuel switch door hinged to the top of the top plate, an ash removal door hinged to the front of the heat recovery assembly, and an air inlet opened on the right side of the combustion assembly;

The combustion chamber has an installation cavity inside and a vibrating conveyor plate is provided inside the feeding port. A vibrating motor is provided on the vibrating conveyor plate. The combustion chamber has an air chamber inside and a blower is fixedly installed inside. An air outlet is provided between the combustion chamber and the heat recovery chamber.

[0009] Furthermore, the bottom end of the conveying cylinder extends into the interior of the exhaust port, and the fuel switch door connects to the top of the fuel storage chamber.

[0010] Furthermore, the ash removal door is located on the front of the combustion chamber, the right end of the air supply pipe extends into the interior of the air inlet, and the left end of the air supply pipe extends into the interior of the air chamber.

[0011] Furthermore, the energy-concentrating chamber is located above and connected to the combustion chamber, and there are three energy-concentrating chambers.

[0023] The combustion assembly 3 includes a combustion chamber 301, which is fixedly installed on the right side of the top of the base 1. The combustion chamber 301 has a fuel storage chamber 302 inside and an air supply pipe 303 fixedly installed inside. A feeding port 304 is provided between the combustion chamber 301 and the heat recovery box 201. The combustion chamber 301 has an installation cavity 305 inside. A vibrating conveyor plate 306 is provided inside the feeding port 304. A vibrating motor 307 is provided on the vibrating conveyor plate 306.

An air supply outlet 311 is provided between the combustion chamber 301 and the heat recovery box 201.

[0024] In this embodiment, the vibration motor 307 drives the vibration conveyor plate 306 to vibrate, conveying semi-coke to the top of the internal mesh 209 of the combustion pan 208 for heat dissipation. The top of the combustion pan 208 is set to a more inclined surface to prevent coking.

[0025] In this embodiment, the blower 310 sends air downwards to the internal partition 209 of the combustion disc 208 to improve combustion efficiency.

[0026] In this embodiment, the heat generated by the combustion of semi-coke will be concentrated in three energy-concentrating chambers 203 and then enter the interior of the energy-concentrating warehouse 205 through the inlet 206 via the delivery pipe 204 for further energy concentration.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, store the semi-coke inside the fuel storage chamber 302;

[0029] 2) Then the vibrating conveyor plate 306 vibrates, conveying semi-coke into the combustion pan 208;

[0030] 3) The blower 310 supplies air to the interior of the combustion disc 208;

[0031] 4) Finally, the heat generated by the combustion of semi-coke will be concentrated in three energy-concentrating chambers 203 and then enter the interior of the energy-concentrating chamber 205 through the inlet 206 via the delivery pipe 204.

[0032] In summary, this high-efficiency semi-coke boiler, which is less prone to coking, features an energy-concentrating chamber 205 installed above the combustion pan 208, and the conveying pipe 5 is moved below the energy-concentrating chamber 205. Once the energy-concentrating chamber 205 reaches heat saturation, it draws away the negative pressure, retaining heat. The increased slope of the combustion pan 208 ensures complete fuel combustion, making it easier for ash and slag to fall off and preventing coking. The heat energy conversion rate is improved from 65% to 87%, solving the problems of large heat loss and coking during combustion, which are common in traditional semi-coke boilers and lead to difficult internal cleaning.
