Introduction

Industrial fuel heating devices are commonly known as fuel furnaces, which usually include three heat sources. coal, oil, and gas, covering low, medium, and high temperature ranges.

It is suitable for different heating and heat treatment processes such as normalizing, tempering, annealing and aging, including push rod type, roller bottom type, stepping type, rotating bottom type and many other furnaces.

The type structure is widely used in our country, and it is called an industrial furnace in parallel with the electric heating device. For a long time, the output value of fuel heating devices has been Although the domestic and foreign market share of heat is as high as 60% to 70% (especially gas stoves are highly efficient and cheap, with burners and pulse combustion control The development of technology has been continuously promoted and applied), but the principle of product classification of fuel heating devices is not clear, the level is not clear, and the standard system is not perfect. for Grasp the technical basic conditions of the product from the source, as a comprehensive electromechanical complete set of heating equipment, refer to the furnace type structure and thermal engineering system of the electric heating device For technical requirements such as temperature and production use, a series of standards of GB/T 20115 "Basic Technical Conditions for Industrial Fuel Heating Installations" are formulated. GB/T 20115 It aims to stipulate the product classification of industrial fuel heating devices and the requirements in terms of design, manufacturing, safety, energy saving and environmental protection, performance and complete sets.

To meet the requirements, it is planned to consist of 9 parts.

---Part 1: General part. The purpose is to specify the general technical requirements for various fuel heating devices.

--- Part 11: Fuel, combustion method and combustion device. The purpose is to specify the types of fuels and combustion methods that meet the needs of the production process.
