Comprehensive Plan for Waste Coal Use and Policy Recommendations
The team of consultants for this component will consist of (i) one coal engineer and team leader, (ii) one power economist (financial management), and (iii) one environment specialist. Each will be needed for 2 person-months on an intermittent basis. The team must have at least 5 years of experience in studying coal-based power generation. The consultants will
(i) identify resource conditions for waste coal use, including (a) physical-geographic conditions at the Pingshuo coal mine; (b) geologic features in the area (e.g., coal seams, coal quality, coal reserves, and coal mining ); and (c) waste coal resources (e.g., outputs and grade of the waste coal);
(ii) identify key aspects of waste coal use, including (a) power generation at the Pingshuo coal mine, (b) construction materials, (c) chemical products, and (d) land reclamation;
(iii) conduct a benefit analysis of waste coal use, taking into account social benefits (e.g., employment generation and health impacts) and environmental benefits (e.g., reduction of waste coal heaps, raw coal production, carbon dioxide, sulfur dioxide, and nitrogen oxide, and improvement of ground water quality);
(iv) establish a compliance mechanism for the implementation of the waste coal use plan that includes (a) compliance with laws and regulations, (b) reinforcing implementation guidelines, (c) emphasizing technology innovation and advancement, and (d) improving incentives to comply with laws and regulations;
(v) recommend reforms to remove barriers to large-scale waste coal power plants; and
(vi) prepare a comprehensive plan and/or guidelines for waste coal use at the Pingshuo coal mine, and make the necessary policy recommendations.
Introduction of Advanced Energy-Efficient Technologies
The team of national consultants for this component will consist of a (i) boiler design specialist, (ii) thermodynamics specialist, (iii) dynamics specialist, (iv) clean combustion specialist, (v) material specialist, (vi) circulating fluidized bed combustion (CFBC) boiler debugging specialist, and (vii) CFBC boiler operation specialist. Each will be needed for 6
person-months on an intermittent basis. The team will have (i) at least 10 years of experience in designing and implementing CFBC boilers; (ii) grade-A certificates in manufacturing equipment , authorization in designing boilers at the national grade-A level, and designing and manufacturing pressurized containers at the national AR1 grade; and (iii) experience in designing or manufacturing 300-megawatt (MW) CFBC boilers. The consultants will:
(i) review existing technology of 600-MW supercritical CFBC; research and develop its key components; and conduct a detailed feasibility analysis on these key components such as wind chambers, cloth air deflectors and wind hats, combustion chambers, separators, loop seals, outside-sets of heat exchangers, and air preheaters;
(ii) study thermal design methods, hydrodynamic force calculation methods, technical feasibility of outside-sets of heat exchangers, and antirubbing technology for 600-MW supercritical CFBC chambers, including (a) based on CFBC thermal design methods, conduct detailed analyses to identify advantages and difficulties of 600-MW supercritical CFBC thermal calculation technology, propose corresponding technical measures, complete thermal calculations for the boiler’s technical design, and proof the accuracy of the result; (b) analyze the heat-current density distribution of combined large-scale CFBC, study 600-MW supercritical CFBC hydrodynamic force computational methods, conduct hydrodynamic force calculations to propose a boiler technical plan, and proof the accuracy of the results; (c) proof the technical maturity and feasibility of outside-sets of heat-exchanger technology, and prepare a technical design of outside-sets of heat exchangers; and (d) based on the analysis of the existing antirubbing technology, prepare a feasibility plan;1
(iii) research and develop the selection, allocation, and design of key auxiliary equipment2 of 600-MW supercritical CFBC, including (a) based on the existing slag cooler technology, select design of a slag cooler, confirm its feasibility, and propose a layout plan; (b) propose an arrangement plan for the boiler’s air blower system, analyze essential air blowers, select a design proposal for their regulation method, and confirm the feasibility; and (c) confirm feasibility to meet emission standards by adding limestone powder to the boiler for desulphurization, and propose a relevant technology plan;
(iv) prepare a comprehensive technical due diligence report of 2 x 600-MW supercritical CFBC and air-cooled generating sets.
