1.0.2 This code is applicable to the design of such constructed, extended and renovated fossil fired power plants with parameters at or below high pressure and high temperature, power per unit less than 125MW, adopting the direct combustion mode and mainly combusting solid fossil fuel.
1.0.3 In addition to the requirements stipulated in this code, the design of small fossil fired power plant also shall comply with those in the current relevant ones of the nation.
3 Basic Requirements
3.0.1 Design of power plant must conform to the state laws and regulations as well as the requirements of the relevant policies such as energy conservation and environmental protection.
3.0.2 Design of power plant shall be carried out in accordance with capital construction procedure and the profundity of its contents shall meet the requirements of the current relevant standards of the Nation,
3.0.3 Type of power plant shall meet the following requirements.
1 Constructing the heating type power plant in an economical and rational heating range according to the urban central heating planning and combined heat and power generation planning and in consideration of the property and size of heating load.
2 Constructing the enterprise self-supply thermal power plant of appropriate scale in accordance with the heating electrical load demand of enterprise.
3 Shall preferentially construct small hydropower or renewable energy power plant at the
region where the power grid is difficult to reach; where the conditions of small hydropower and renewable energy are unavailable or at the region where the local coal resource is abundant, traffic is difficult and faces electric power shortage or no electric power, condensing power plant of appropriate scale shall be constructed in accordance with local conditions on basis of the urban regional power planning.
4 At regions with permissible conditions, the heating, power and cooling combined heating
power plant should be popularized.
3.0.4 Selection for the pressure parameter of the units of power plant should consider the short term and long term uniformly and should meet the following requirements.
1 For the thermal power plant, the steam extraction unit with power per unit of or above Grade 25MW and the back pressure unit of 12MW should be selected with high-voltage parameters; the steam extraction unit with power per unit of 12MW and the back pressure unit of 6MW should be selected with the high-voltage, sub-high-voltage or medium-voltage parameters; and the units with power per unit of or below 6MW should be selected with the medium-voltage parameters.
2 For condensing power plant, if the power per unit is of or above Grade 50MW, the high-voltage parameters should be selected; if the power per unit is below Grade 50MW, the sub-high-voltage or medium-voltage parameters should be selected.
3 Units in one same power plant should adopt the same kind of parameters.
3.0.5 Design of power plant shall meet the requirements the state electric power development and enterprise development planning, the design of thermal power plant shall meet the requirements of the urban central heating planning and combined heat and power generation planning, and the design of enterprise self-supply thermal power plant shall meet the requirements of enterprise process system on heating parameters.
3.0.6 Design of power plant shall sufficiently and rationally utilize the resource condition at site and conduct overall planning in accordance with the planning capacity.
3.0. 7 Design of extended and renovated power plants shall consider fully in combination with the characteristics in such aspects as original general layout, equipment layout of original production system, original building structure and operation management experience.
3.0.8 Enterprise shall make overall planning for the design of its self-supply power plant and shall not set repeated systems, equipment or facilities for the power plant.
3.0.9 The design life of the process system of power plant shall be designed of 30 years.
