Above technical characteristic constitutes embodiments of the invention, and it has stronger adaptability and implementation result, can basis
It is actually needed the non-essential technical characteristic of increase and decrease to meet the demand of different situations.
The embodiment of the present invention uses process：
After technical scheme 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 carry out coal according to traditional outdoor temperature and return water temperature curve
Charcoal stoking operation, is not required to carry out big adjustment, only energy need to be put into raw coal and fully be burnt above.Because coal is fully fired
Burn 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 declines.And
Typical high power circulating pump is changed to after multiple-limb small-power branch balanced recycle water pump, under branch's balanced recycle water pump overall power
Drop, power savings are obvious.
The centralized heating boiler plant of certain group field, installation 7MW and 14MW hot water chain furnaces are each one, 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.Larger due to circulating radius, 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 present invention is provided, branch's balanced recycle pump is installed in three branched pipes, power is respectively：
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）.Through a heating
Ji Yunhang, heating effect be improved significantly, economize on electricity effect project（By operational efficiency 74%, heating duration was calculated by 180 days）：
{（110×2）-（45+22+15）}×24×180×74%=441158（KW.h）, 0.46 yuan/KW.h of local electricity price, saving electricity
Take 441158KW.h × 0.46 yuan/KW.h=202932 first, coal consumption drops to 44kg/ ㎡ by 47kg/ ㎡ over the years, save raw coal 14.1
Wan ㎡ ×（47-44）kg/㎡=423（Ton）, 185 yuan/ton of local coal price, 423 tons × 185 yuan/ton=78255 yuan of expense of saving.
The both applicable heating system identical heating system of the present invention（Such as radiator heating or floor heating mode）, it is also suitable mixed
Close heating system（Radiator and floor heating mix）, only will need to be supplied using radiator using the branched pipe return water temperature ratio of floor heating heat supply
Warm branched pipe return water temperature reduces by 6 DEG C.
