WNS series gas / oil fired hot water boiler adopts advanced structure, the boiler structure is compact, occupies a small area, installs quickly. The boiler adopts advanced mechatronics automatic control technology, high quality silicic acid encryption and insulation, reduce heat loss. Horizontal industrial boiler composes furnace body, access door hole, front and rear smoke chamber, insulation layer cover, burner interface, pipes, valves and instruments, platform and stairs, instruments and safety devices, supporting accessories, electrical control cabinet.
By installing waste heat boilers in these hot gas streams, steam can be produced and used to power a generator (producing electricity) or to drive a fan (offsetting electricity consumption). With temperatures in excess of 600°F, these systems can be cost effective. Customized Cement Kiln Heat Recovery Solutions
Waste heat Recovery means allowing the waste heat to leave the process, but converting into electricity before it is discharged at lower temperature level to the environment. Therefore, after the efficiency of a cement plant has been driven to the economic optimum, the remaining waste heat is converted into electricity.
21MW Waste heat recovery system for Pukrang cement plant: Hakan Uvez, Asia Cement PLC (Thailand) Filmed at Cemtech Asia 2015, 21-24 June, Grand Hyatt, Bangkok, Thailand
WASTE HEAT RECOVERY POWER PLANTS IN CEMENT INDUSTRY S K Gupta / S K Kaul Holtec Consulting Private Ltd., Gurgaon, India ABSTRACT In a cement plant, nearly 35% heat is lost, primarily from the preheater and cooler waste gases.
Waste Heat Recovery for the Cement Sector 1 Waste Heat recovery (WHr) is a proven technology, but until now WHr uptake has been limited except in China. As early as the 1980s, Japanese companies spear-headed the introduction of WHR power systems in the cement industry. Currently, there are a range of commercially-
RD&D to advance waste heat recovery technologies. Technology needs are identified in two broad areas: 1) extending the range of existing technologies to enhance their economic feasibility and recovery efficiency, and 2) exploring new methods for waste heat recovery, especially for unconventional waste heat sources.

2. Waste Heat Recovery in the Turkish Cement Industry: Current Status and Project Experience.17 Forty Percent of Existing Clinker Capacity Has Implemented WHR..17 Turkey's Cement Industry Has Seen Substantial Adoption of Waste Heat Recovery
Criterion 1 The project utilizes waste heat from a cement production facility by waste heat recovery (WHR) system to generate electricity Criterion 2 WHR system consists of a Suspension Preheater boiler (SP boiler) and/or Air Quenching Cooler boiler (AQC boiler), turbine generator and cooling tower
Energy generation in cement works arises from the waste heat collected from the burning process in the cooling and pre-heating stages. The energy harnessed is used for auxiliary power. The waste heat can be converted into electrical energy by means of a steam turbine generator.
Heat recovery for power production may not be feasible in plants where the waste heat is used in raw mills to extensively dry the raw material - which offers a more efficient and economic option (US EPA, 2010. p22). It has been reported that there are at least 33 cogeneration units in various cement plants with total capacity about 200 MW in Japan.
