Clinker Coolers

Clinker Cooling Department is one of the most important parts of cement production line and plays a significant role. Consequently, cooler performance necessitates comprehensive studies, analyses, and controls to contribute to saving energy. Today modern clinker coolers would include some of the following provisions which conducts the design and selection of a clinker cooler.

●    Low capital cost,
●    Optimum cooling rate for good quality of clinker,
●    Low clinker outlet temperature,
●    Minimum possible impact upon the environment,
●    High heat recovery,
●    Low power consumption,
●    Low wear and maintenance cost,
●    Reliable to operate

All these requirements must be accomplished efficiently and simultaneously in modern clinker coolers which are designed by different cooler manufacturers.
For having a desirable performance of a clinker cooler, any designer looks at these criteria and tries to optimize the design. Also some activities can be considered to develop cooler performance while it is already installed and operating. Based on energy audit and performance tests of clinker cooler, any plant can make necessary decisions to optimize its own clinker cooler performance.

From the viewpoint of energy/fuel saving and maintenance issues, the cement manufacturers always desire to get their cooling system be checked and evaluated based on the measurements through an audit operation. The development of clinker cooler performance by energy audit comprises a comprehensive measurements and analyses taking into account of the plant’s previous regular records of some important values. After getting evaluated of the measurements, the bottlenecks of cooling can be easily recognized from aspects of process or mechanical issues.

Thank to our great academic and professional background in clinker cooler design, cooler performance audits, and related calculations, ESS Tech. Eng. provides a bankable engineering and consultancy services to the cement producers.

Rotary Dryers

Rotary dryers are critical component in many industrial processes most commonly used in:

●    Mineral Industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal, iron sulphate, filter cakes, sewage sludge,
●    Food Industry mainly for drying sugar and some grains
●    Other granular materials

ESS Technology Engineering provides complete engineering and design services involving sizing and general arrangement, 3D / 2D general views, preparation of entire fabrication details, and all technical and process parameters.

Audits (Partial or Complete)

An energy audit and conservation project can be carried out in the cement plant to assess the performance of its various sub-sections and utilities such as pyro-process system, fans, compressors and etc.

With its energy-saving solutions ESS Tech. Eng. defines an objective to provide a frame work for executing an energy audit in a cement plant and assists the clients to achieve the above solutions. Such a program is applicable through the following sub-sections by submitting detail audit, evaluation, and heat balance calculations.

●    Pyro-process System (audit, calculation, and heat balance in Pre-heater, Kiln, Clinker Cooler, Fans)
●    Grinding Process

Filtration and De-dusting

Most of the industries, in particular cement production industry requires vast amount of non-renewable resources and fossil fuels. The cement industry, as well as other industries contributes significantly to the imbalances of the environment; in particular air quality. The key environmental emissions are Nitrogen Oxides (NOx), Sulphur Dioxide (SO2) and Grey Dust.

In accordance with emission laws and other statutory rules and regulation for keeping air clean, dust emission as well as pollutant gases must be strictly limited in the industries. In this regard, as ESS Technology Engineering, it’s our pleasure to make a contribution to environmental protection by offering engineering and consulting services in the following fields.

●    Dust Collectors (Bag Filters, Cyclones, Dust Precipitators)
●    Exhaust Gas Cleanings Systems
●    Toxic Gas Cleaning Systems
●    Scrubbers and Chemical Adsorbers
●    SNCR systems in cement plants and other industries

Mechanical Equipment

Like other fields, ESS Tech. Eng. performs services in engineering and design of some mechanical equipment which are listed below. We can also cover the customers’ requirements in relationship with manufacturing processes by collaborating with our solution partners.

●    Belt Conveyors, Bucket Elevators, Screw Conveyors
●    Air Slides
●    Fan and Ventilators
●    Raw material and clinker sample takers
