introduction

Industrial boilers are the main thermal power equipment in my country. They are widely used and in high demand. They play an important role in industrial production and military and civilian life. With the adjustment of national energy development strategy and the promotion of national policy on air pollution control, the utilization of new energy and renewable energy has driven the industrial Under the background that my country's economy has entered a new era, industrial boiler enterprises have actively adapted to the In line with the needs of market and economic development, we have continuously adjusted our product structure, increased our investment in research and development of new products, and accelerated the development of large coal-fired boilers and fuel-fired The development of gas boilers, biomass boilers, pulverized coal industrial boilers, waste heat boilers, electric heating boilers, etc. has accelerated. According to the requirements of the Technical Committee's boiler standard system optimization plan, GB/T 1921-2004 "Industrial Steam Boiler Parameter Series", The two national standards GB/T 3166-2004 "Hot Water Boiler Parameter Series" were integrated and revised into GB/T 1921 "Technical Specifications for Industrial Boilers". This document proposes the performance, design, manufacture, inspection and testing, installation, commissioning, acceptance and use of industrial boilers. TSG11 "Boiler Safety Technical Regulations" and TSG91 "Boiler Energy Saving and Environmental Protection Technical Regulations" have basic requirements for safety, energy saving and environmental protection, and are consistent with boiler This document is the core construction standard and other boiler product standards. It is one of the important standards of the "Standard for Specific Boiler Construction Methods", which will lead the technological innovation of industrial boilers and provide a basis for further improving the production of industrial boilers. It plays an important role in product quality and high-quality development of the industry. Technical Specifications for Industrial Boilers 1 Scope This document specifies the parameter series and model compilation, performance, materials, design, manufacturing, inspection and testing, painting, packaging, nameplate, etc. of industrial boilers. Brands, signs and random documents as well as installation, commissioning, acceptance and operation. This document applies to industrial boilers. Non-power station boilers with rated steam pressure greater than or equal to 3.8 MPa and rated working pressure less than Hot water boilers and organic heat carrier boilers with a rated thermal power of 0.1MPa or greater and equal to 0.1MW shall be used for reference. Note. The pressure values mentioned in this document refer to gauge pressure. 2 Normative references The contents of the following documents constitute the essential clauses of this document through normative references in this document.
