5. Prevention of energy loss due to radiation, conduction, resistance, etc.

Construction work for thermal insulation of pipes and facilities used in transporting heating media and process fluids and of heating facilities, etc. (heating facilities) shall be conducted as stipulated in JIS A9501 Standards for Implementation of Heat Insulation Construction and Other Standards.
When building new industrial furnaces starting from the furnace bed, furnace wall thermal insulation shall be improved by taking heat insulation measures based on the values of outer furnace wall surface temperature as specified in Appendix Table 3 (A) (for industrial furnaces whose operating time per day does not exceed 12 hours and whose furnace temperature exceeds 500C, the outer furnace wall surface temperature shall be as specified in Appendix Table 3 (A) or more than 70% of the inner furnace wall surface shall consist of the heat insulating substance with the weighted average value of bulk density 1.0 or under. For existing industrial furnaces, heat insulation measures shall be taken with the values specified in Appendix Table 3 (A) as standards outer furnace wall surface temperature.

Management standards shall be implemented for measurement and recording of items required for determining heat loss including outer furnace wall surface temperature, heated object temperature, waste gas temperature, etc., for individual facilities for heating, etc., and of items required for improving heat loss, and based on standards, items shall be measured regularly, results shall be used for analyzing heat balance, etc., and records shall be preserved.

Management standards shall be implemented for maintenance and inspection of items as measures for preventing heat loss due to heat insulating construction of facilities using heat, and such items shall be put to regular maintenance and inspection based on the standards.
To prevent steam leakage due to malfunction of steam traps, management standards for maintenance and inspection shall be implemented, and maintenance and inspection shall be regularly conducted based on standards.

Management standards shall be implemented for maintenance and inspection of items as measures for preventing heat loss due to heat insulating construction of facilities using heat, and such items shall be put to regular maintenance and inspection based on the standards.
To prevent steam leakage due to malfunction of steam traps, management standards for maintenance and inspection shall be implemented, and maintenance and inspection shall be regularly conducted based on standards.
