Inclined reciprocating boiler grate structure

The structure of the inclined reciprocating boiler grate is divided into two types: one is the more common inclined reciprocating grate, and the other is a water-cooled reciprocating boiler grate that has rapidly developed in recent years. The general inclined reciprocating boiler grate is mainly composed of several parts, including movable grate bars, fixed furnace, grate bar transmission mechanism, and reciprocating mechanism.

Introduction to Boiler Grates

The chain grate boiler grate is a type of mechanized combustion equipment that is widely used in industrial boilers, but its application range is limited. The combustion method of the chain grate boiler grate is generally moving fireboat combustion. The ignition condition is limited ignition, and the fuel enters the interior through the coal hopper of the boiler grate. As the boiler grate gradually advances, the burning and consumed coal ash will move to the tail with the movement of the grate.

How to handle the drying of the scale grate?

The scale grate is divided into three parts: the drying furnace, the combustion furnace, and the ash melting furnace. Each section can fully mix the waste during the drop, scale grid, and when the waste falls, flipping and enhancing combustion. Each grate section uses a vertical extraction reciprocating motion, which can push back some of the burning waste to accelerate the drying and ignition of the newly incoming waste. A shear knife is installed between the combustion grate and the ignition grate, which can remove block waste, enhancing the full contact of waste with air, making the combustion of waste cleaner.

What is a scale grate?

The component that accumulates solid fuel and burns it effectively on a grate or industrial furnace. The entire furnace mainly consists of two parts: the frame and the grate. The grate plates are generally made of cast iron, and after assembly, they maintain the necessary ventilation gaps between the grate and the carvings. Often, a separate adjustable air supply chamber is set up below the grate, allowing air to enter the fuel layer through the gaps for combustion. The ash residue after combustion is discharged by manual or mechanical methods. The furnaces can be fixed, mobile, reciprocating, vibrating, or lower-level types.

This section explains the maintenance of the grate and the structure of the reciprocating grate.

The following explains the maintenance of the scale grate and the structure of the reciprocating grate. The scale grate uses electricity as energy, utilizing resistive heating and electromagnetic induction heating, to heat the heat carrier water and organic heat carrier (thermal oil) to a certain parameter temperature and pressure through the heat exchange part of the boiler, outputting the thermal energy of the rated working medium to the outside.

Current Status and Future of Waste-to-Energy Technology from the Perspective of Yongning Grate

Currently, there are three main types of waste incineration technology: fluidized bed combustion technology, staged combustion technology, and rotary combustion technology, corresponding to the incinerators such as Yongning grate, rotary kiln, and fluidized bed furnace. The main technologies used in China's waste-to-energy industry include Yongning grate technology and fluidized bed combustion technology.

The manufacturer of the flake grate will explain the installation matters of the flake grate.

The manufacturer of the grate will explain the installation matters of the grate. For waste with different calorific values, while distributing different air volumes and providing combustion air, the grate drive can be independently controlled, making it easy to control the supply and air volume of different combustion areas separately. A rolled plate structure is set between each row of grates, preventing waste leakage between adjacent grates, and there is almost no friction between the same row of grates. An elastic wear-resistant layer is set at the front of the grate, reducing wear and increasing the lifespan of the grate. Cooling steel plates are installed on the bottom surface of the grate plates, ensuring good cooling effect of the primary air, and the grate is hardly damaged.

Research on the Technology of Municipal Solid Waste Incineration Furnace in Yongning

The Yongning grate garbage incineration power generation technology has many advantages and is suitable for large-scale processing of high calorific value unsorted household waste. This article introduces the current technical status, development trends, and classification of Yongning grates in China, and summarizes and analyzes the main technical characteristics of commonly used mechanical grate incinerators. By introducing the working principle of the Yongning grate and conducting a technical analysis and comparison of its functions, this provides important reference value for the design, application, research and development, and performance optimization of mechanical grate incinerators.
