T/CCIAC 003-2022 The technical specifications for lime kiln used in the production of calcium carbide

Scope

Scope: This document specifies the terms and definitions, technical requirements, test methods, safety regulations, and evaluation methods for the acceptance of lime kilns used in the production of calcium carbide. This document applies to the acceptance of lime kilns used in the production of calcium carbide, including sleeve kilns, rotary kilns, double-chamber kilns, double-beam kilns, and other kiln types suitable for the production of lime for calcium carbide. This document applies to the acceptance of lime kilns used in the production of calcium carbide with an altitude not exceeding 2,000m. Lime kilns used in the production of calcium carbide with an altitude exceeding 2,000m may refer to this document for implementation. This document applies to the assessment of the actual production situation by lime production enterprises used in the production of calcium carbide, as well as the acceptance of newly built and expanded lime kilns used in the production of calcium carbide. Main technical content: Based on the requirements of the calcium carbide industry for lime production and stable system operation, combined with the operating characteristics of the calcium carbide-lime circular industry chain and the characteristics of calcium carbide furnace gas, requirements are proposed for the process, main structure, internal refractory materials, heat consumption, power consumption, lime quality, pollutant emissions, and safety facilities configuration of lime kilns used in the production of calcium carbide. Test and inspection methods are specified, and calculation methods are defined.
