To　achieve　the　goal　of　carbon　neutrality　for　the　application　of　industrial　heating　by　recovery　waste　heat,　the　concept　of　dual-temperature　condensation　and　dual-temperature　evaporation　is　proposed　for　the　hightemperature　heat　pump　(HTHP)　by　introducing　the　techniques　of　ejector　and　two-stage　compression.　The　energy,　exergy,　emission,　and　economic　models　are　developed　and　optimized　for　the　two　new　proposed　systems.　Then,　the　energy　consumption,　CO2　emissions　and　cost　(LCC)　during　the　whole　life　cycle　are　compared　with　five　existing　heat　pumps　and　four　traditional　boilers.　The　highest　coefficient　of　performance　(COP)　of　heat　pump　(HP)　can　be　got　when　intermediate　water　temperature　on　the　heat　sink　side　is　optimum.　The　new　proposed　systems　have　better　performances　than　the　other　five　HTHPs.　During　the　rated　working　condition,　discharge　temperature　decreases　by　the　use　of　dual-temperature　condensation　and　dual-temperature　evaporation　HP　with　an　ejector　(EjDCDE).　The　optimal　COP　of　Ej-DCDE-2　is　4.25,　which　is　11.55%　and　1.43%　higher　than　dual-temperature　condensation　and　single-temperature　evaporation　HP　and　Ej-DCDE-1,　respectively.　The　exergy　destruction　of　Ej-DCDE-2　is　reduced　by　27.88%　compared　with　basic　heat　pump　(Base).　Moreover,　Ej-DCDE-2　has　the　lowest　primary　energy　consumption　of　14.62　ktoe,　22.19%　and　25.09%　lower　than　Base　and　oil-fired　boiler　during　the　total　working　period,　respectively.　In　general,　HTHPs　have　lower　carbon　dioxide,　gaseous　and　particular　pollutant　emissions　compared　with　boilers,　especially　Ej-DCDE-2.　Finally,　Ej-DCDE-2　has　the　minimum　LCC,　which　is　14.67%　and　11.75%　less　than　Base　and　coal-fired　boiler.　Ej-DCDE-2　shows　the　most　potential　advantages　of　all　the　heating　solutions　and　is　recommended　to　replace　traditional　boilers　for　industrial　heating.
