The utility model embodiment uses process：
After the technical solution of the utility model is implemented, operation is simple and feasible for whole regulating of heating net, and heating effect is improved,
Energy-saving effect（Coal consumption, power consumption）It is obvious.After heat supply network balance, fireman only need to be bent according to traditional outdoor temperature and return water temperature
Line carries out coal stoking operation, is not required to carry out big adjustment, and only energy need to be put into raw coal fully burns above.Because coal is obtained
To fully burning and be not required to improve whole system heat for respective regions user indoor temperature is not up to standard again so that coal consumption
Decline.And after typical high power circulating pump is changed to multiple-limb small-power branch balanced recycle water pump, branch's balanced recycle water pump is whole
Body power drop, power savings are obvious.
The centralized heating boiler plant of certain group field, installs each one of 7MW and 14MW hot water chain furnaces, is supplied using direct-furnish mode
Heat, the Wan ㎡ of area of heat-supply service about 14.1, but heating range is wider, and circulation radius is larger, and three branched pipe farthest users are apart from boiler
Room about 1.4km, it is nearest only less than 200m.Design cycle pump three（Dual-purpose one is standby）, power 110KW, lift 56m, flow
540m³/H.Because circulation radius is larger, terminal temperature difference complaint is more, and the user nearer apart from boiler room is forced to open a window.
Using after the technical scheme that the utility model is provided, branch's balanced recycle pump, power point are installed in three branched pipes
It is not：45KW (the Wan ㎡ of area of heat-supply service 7.6), 22KW（The Wan ㎡ of area of heat-supply service 3.5）、15KW（The Wan ㎡ of area of heat-supply service 3）.By one
The operation of individual Heating Season, heating effect be improved significantly, economize on electricity effect is protruded（By operational efficiency 74%, heating duration is pressed 180 days
Calculate）：{（110×2）-（45+22+15）}×24×180×74%=441158（KW.h）, 0.46 yuan/KW.h of local electricity price,
Power cost saving 441158KW.h × 0.46 yuan/KW.h=202932 units, coal consumption drops to 44kg/ ㎡ by 47kg/ ㎡ over the years, saves former
The Wan ㎡ of coal 14.1 ×（47-44）kg/㎡=423（Ton）, 185 yuan/ton of local coal price, 423 tons × 185 yuan/ton of expense of saving=
78255 yuan.
The utility model both applicable heating system identical heating system（Such as radiator heating or floor heating mode）, also fit
Use composite heating mode（Radiator and floor heating mix）, only radiating need to will be used using the branched pipe return water temperature ratio of floor heating heat supply
6 DEG C of the branched pipe return water temperature reduction of device heating.
