8　Coal Handling System

8.1　General Requirements

8.1.1　The coal handling system of newly-built power plants shall be designed based on the specific conditions of the power plant，such as the planned capacity，kinds of coal，natural environment，and coal transportation and supply mode.Whether the coal handling system is built once for all or in phases shall be subjected to techno-economic comparison when necessary.

8.1.2　The coal handling system of an extended power plant shall be designed with reference to the operation production systems and layout characteristics of the existing power plant to fully utilize the existing facilities and minimize the impact of the extension construction on the production activities.

8.1.3　Belt conveyors should be used for the coal handling system.When the total coal consumption is less than 60t/h，the coal handling system may be designed in single line.When the total coal consumption is 60t/h and above，the coal handling system may be designed in dual lines.

8.1.4　The operating hours of the coal handing system around the clock shall be determined in accordance with the following requirements:

1　If two-shift system is used，the total working hours should not be more than 11h.

2　If three-shift system is used，the total working hours should not be more than 16h.

3　The working shift system of the coal handling system shall accommodate the total effective capacity of the coal bunkers of the boiler.

8.1.5　The output of the coal handling system shall be determined based on the total hourly coal consumption of all boilers in the power plant when operating under BRL condition（hereinafter referred to as the total coal consumption），and shall comply with the following requirements:

1　The three-shift system should be used for dual-line coal handling system with the output of each line at least 135% of the total coal consumption.

2　The two-shift system should be used for the single-line coal handling system with an output at least 300% of the total coal consumption.
