Изобретений относитс к области теплоэнергетики и предназначено дл подогрева питательной воды турбоустоновки на тепловых электрических станци х.The invention relates to the field of heat and power engineering and is intended to preheat the feedwater of a turbo-sounder at thermal power plants.
Изнестны системы регенеративного подогрева питательной воды турбоустановки, содержащие подсоединенные к паропроводам отборов пара подогреватели низного 1Г111Д) и высокого давлени (ПВД) с питательным насосом между ними и трубопровод слива дренажа из подогреват|злей высокого давлени , включенный между насосом и. подогревател ми низкого давлени The regenerative feedwater heating systems of the turbine installation containing low-pressure 1G111D and high-pressure (HPT) heaters connected to steam pipelines with a feed pump between them and a high-pressure heated drain pipe connected between the pump and are connected. low pressure heaters
Однако в известных, так называемых бездеаэраторных, системах регенеративного подогрева дренаж из ПЕД подают при помощи специального насоса.However, in the well-known, so-called deaerator-free, regenerative heating systems, the drainage from PED is supplied with a special pump.
Дл обеспечени необходимого подпора дл этого насоса уста навливают ПВД на более высокой отметке. Кроме того, установва такого дренажного наооса неTo provide the necessary backwater for this pump, the PVD is installed at a higher level. In addition, installing such a drainage pump is not
f. устран ет необходимости предусматривать каскадный сброс дренажа в ПНД на случай выхода этого насоса из стро , что еще больше усложн ет и удорожает систему.f. eliminates the need to provide a cascade discharge of drainage in the HDPE in the event that this pump fails, which further complicates and increases the cost of the system.
, Целью изобретени вл етс повышение экономичности и снижение капитальных затрат.The aim of the invention is to increase the economy and reduce capital costs.
Поставленна цель достигаетс тем, что в трубопровод сливаThe goal is achieved by the fact that in the pipeline drain
, дренажа (из ПВД) включен расширитель , соединенный с паропроводом отбора пара последнего по ходу питательной воды подогревател давлени ., a drain (from LDPE), an expander is connected, connected to the steam pipeline of the latter's steam along the feedwater of the preheater.
0На чертеже дана схема предложенной системы регенеративного подогрева.0The drawing shows a diagram of the proposed regenerative heating system.
Система содержит подогреватели I и 2 низкого давлени (ПНД)The system contains I and 2 low pressure heaters (HDPE)
