1、 The introduction of the fluidized bed furnace for vertical grinding is composed of the main furnace and the auxiliary furnace. There is a partition between the main and auxiliary furnaces, with the upper part connected. The furnace has a square cross-section, and the lower reduction zone of the main furnace is a circular cylinder. There is a gas distribution plate at the bottom. There are 10 layers of baffle plates in the auxiliary furnace. The furnace body is a brick structure with a metal shell. The main and auxiliary furnaces are equipped with three rows of fluidized bed furnace burners at different heights for combustion. In addition, there are temperature and pressure measuring devices.

High temperature fluidized bed furnace is a new type of furnace that can burn low-quality coal. In terms of combustion method, it overcomes the shortcomings of layer combustion furnace and spray combustion furnace. It is a new type of fluidized bed combustion furnace, where the fuel is crushed into particles below 10mm and evenly fed into the furnace by speed regulating machinery. Controllable high-pressure air is injected into the furnace bed through the air cap hole on the air distribution plate, and the fuel is fluidized and boils under the action of high-pressure air, producing high-temperature hot flue gas, The combustion in the furnace has good controllability by controlling the coal supply, air volume, air pressure, and exhaust gas temperature; Fluidized bed furnaces can use inferior fuels, generate less nitrogen compounds, and have significant environmental advantages in easy desulfurization.

The main characteristics and advantages of high-temperature fluidized bed furnaces:

(1) Good fuel adaptability, bituminous coal, anthracite and various low-quality fuels, such as coal gangue, stone coal, coal slag, etc. can be used as fuel;

(2) The fuel preparation is simple, and the raw coal can be crushed to below 10mm before being put into the furnace for use;

(3) High combustion efficiency, small combustible coal particles, sufficient combustion, carbon particle burnout rate of over 98%, thermal efficiency of over 95%;

(4) Stable heating, uniform temperature, wide range of heating adjustment, stable and adjustable heating temperature below 1000 ℃.

(5) The furnace top adopts concave convex groove refractory bricks with a service life of no less than five years.

2、 Introduction to diesel vertical mill fluidized bed furnace burner: The vertical mill fluidized bed furnace burner uses diesel or heavy oil as fuel, which is called: diesel vertical mill fluidized bed furnace burner, heavy oil vertical mill fluidized bed furnace burner or diesel vertical mill fluidized bed furnace burner, heavy oil vertical mill fluidized bed furnace burner. Heavy oil vertical mill fluidized bed furnace is mainly used in African and Middle Eastern countries and regions.

1. Fuel saving. The diesel burner or heavy oil burner adopts a flame stabilizing disc structure, and uses an air compressor to compress air atomization. The fuel/air mixture is uniform and the combustion is sufficient. If the vertical mill fluidized bed furnace uses high viscosity heavy oil as fuel and auxiliary heating measures are adopted to enhance the fluidity of heavy oil and facilitate atomization combustion. Diesel or heavy oil is sprayed into the furnace of a fluidized bed furnace through a fuel burner, generating a large amount of heat after combustion, which is used to dry slag or mineral powder. Due to the high calorific value, high drying efficiency, and large output of heavy oil and diesel, energy-saving purposes are achieved.

2. Automatic temperature control function. According to the baking temperature, automatic temperature control function can be achieved, and local and remote control functions can be achieved through docking with the central control room, making maintenance convenient.

3. Vertical mill fluidized bed furnaces can be designed with gas or oil coal mixed combustion structures, which can be used for both coal and gas or oil, meeting environmental protection needs while also reducing fuel operating costs for users.

In addition, the burners of vertical mill fluidized bed furnaces are classified according to the different types of gas fuels used: natural gas vertical mill fluidized bed furnace burners, liquefied gas vertical mill fluidized bed furnace burners, light hydrocarbon gas vertical mill fluidized bed furnace burners, blast furnace gas vertical mill fluidized bed furnace burners, coke oven gas vertical mill fluidized bed furnace burners, converter coal gas vertical mill fluidized bed furnace burners, calcium carbide furnace tail gas vertical mill fluidized bed furnace burners, etc, The characteristics of various types of gas fuels can be found on the website: Natural gas burner or by calling (WeChat synchronization): 15713691937.
