l) The combustion diagram and its drawing requirements are added (see 6.2.2);

m) Added automatic combustion control system function (see 6.2.4);

n) Increase the layout and determination method of the furnace main control temperature monitoring point (see 6.2.5);

o) Changed furnace temperature requirements (see 6.2.6, 6.2.7 of the 2008 edition);

p) Deleted the requirement for incineration short-circuit (see 6.2.14 of the 2008 edition);

q) Changed the design life requirements for incinerators and waste heat boilers (see 6.2.10, 6.5.6 of the 2008 edition);

r) Changed the total heat load requirements of the main burner and auxiliary burner (see 6.3.3, 6.2.10 of the 2008 edition);

s) The incinerator should adopt low-nitrogen combustion technology requirements such as flue gas recirculation (see 6.3.4);

t) Changed the allowable deviation of superheated steam temperature (see 6.4.5, 6.4.2.3 of the 2008 edition);

u) Increased the requirements for denitrification agent nozzles (see 6.4.8);

v) Increased performance index requirements for incinerators and waste heat boilers that can be verified by tests (see Chapter 7);

w) Changed the requirements for the thermal ignition loss rate of incinerator slag (see 7.4, 6.2.13 of the 2008 edition);

x) The requirements for the concentration of carbon monoxide in the flue gas exhausted from the waste heat boiler outlet have been added (see 7.5);

y) Changed the design heat efficiency requirements for incinerators and waste heat boilers (see 7.8, 6.5.5 of the 2008 edition);

z) Changed the method for measuring the low-level calorific value of waste entering the furnace (see 8.1, 7.1 of the 2008 edition);

aa) The determination and calculation method of thermal ignition loss rate of incinerator slag has been changed (see 8.4, 7.2 of the 2008 edition);

bb) Added the determination method for waste heat boiler feed water quality indicators (see 8.6);

cc) Changed the requirements for the nameplate of the incinerator (see 10.2, 9.1 of the 2008 edition);

dd) Change the nameplate requirements for waste heat boilers (see 10.3, 9.1 of the 2008 edition);

ee) Change the coating and packaging requirements for incinerators and waste heat boilers (see 10.4, 9.2 of the 2008 edition);

ff) Changed the random document requirements for incinerators and waste heat boilers (see 10.5, 9.3 of the 2008 edition).
