Background technology
In urban district heating system, in order to the intermediary of transfer of heat, also claim heating agent or band hot body. ModernThe heating medium extensively adopting in thermal process is water, because water exists in a large number at occurring in nature, thermal capacity is large,Circular flow cost-effectively in heat transfer process. It is heat supply that urban district heating system also generally adopts waterMedium, with the form of hot water or steam, carries heat from thermal source, delivers to user through heat supply network.
Hot-water heating system is driven and is circulated by water pump, and the flow velocity of water is about 1～2 meter per second, carries radius to reachMore than 10 kilometers. Supply and return water temperature is more definite according to Technological Economy. Chinese city central heating system is being adoptedWhen warm outdoor calculate temperature, design supply water temperature adopts 130 DEG C or 150 DEG C, and return water temperature is 70DEG C. When outside air temperature is during higher than heating accounting temperature, the conventional method that reduces medium temperature regulates. Like thisBoth can reduce the pipeline heat loss in pumped (conveying) medium way, be convenient to again utilize the low-pressure pumping steam of heat supply unit, improve heatThe economic benefit of power plant's heat supply. Because specific heat of water is large, heat storage capacity is high, and therefore heating system operation has fluctuationTime, heat supply situation is still more stable. Hot-water heating system medium leakage loss in service is few, and the required supply water yield is less,The processing requirements of make-up water is also lower.
But in heating equipment, when being heated, water there is the problem that the thermal efficiency is not high at present, and considerableHeat generation dissipation, wasted the energy, be unfavorable for sustainable development.
Utility model content
