An ECONOMIZER is a device which is used to reduce the energy consumption in the system by utilizing energy from process outputs. Economizer is a type of HEAT EXCHANGER which is used for heat transfer between two fluids. Economizer basically reuses waste heat from hot flue gases from boiler and preheats the feed water going to boiler. Thus energy required for generating steam is reduced due to preheated water.
Economizer as a result is a WASTE HEAT RECOVERY UNIT which plays a vital role in improving boiler efficiency.
We design and manufacture economizers for both IBR and NON IBR boilers. We adopt all the IBR rules for design and refer national and international standards and codes for best engineering design of the product. We have our own manufacturing setup which implements best possible manufacturing techniques ensuring fastest production with best quality.
We study the client's process for accurate design and also consider the client's special requirements for assuring customer satisfaction. We also provide AUTOMATION to improve accuracy and reduce labour jobs.
We appreciate your interest in the economizers and request the enquiry for the future transactions.
A FAN is a device which is used to supply mechanical energy to the air or gas.
There are two main kinds of industrial fans:
1. Centrifugal fans
2. Axial-flow fans
CENTRIFUGAL FANS :
Centrifugal fans consist of a wheel or a rotor mounted on a shaft that rotates in a scroll-shaped housing. Air enters at the eye of the rotor, makes a right-angle turn, and is forced through the blades of the rotor by centrifugal force into the scroll-shaped housing. The centrifugal force imparts static pressure to the air. The diverging shape of the scroll also converts a portion of the velocity pressure into static pressure.
There are three main types of centrifugal fans:
RADIAL BLADE FANS - Radial-blade fans are used for heavy dust loads. Their straight, radial blades do not get clogged with material, and they withstand considerable abrasion. These fans have medium tip speeds and medium noise factors.
BACKWARD CURVED BLADE FANS - Backward-blade fans operate at higher tip speeds and thus are more efficient. Since material may build up on the blades, these fans should be used after a dust collector. Although they are noisier than radial-blade fans, backward-blade fans are commonly used for large-volume dust collection systems because of their higher efficiency.
FORWARD CURVED BLADE FANS - These fans have curved blades that are tipped in the direction of rotation. They have low space requirements, low tip speeds, and a low noise factor. They are usually used against low to moderate static pressures.
When we design fan for client, we consider the following points :
1. Volume required
2. Fan static pressure
3. Type of material to be handled through the fan
(For example, a radial-blade fan should be used with fibrous material or heavy dust loads, and non-sparking construction must be used with explosive or inflammable materials.)
4. Type of drive arrangement, such as direct drive or belt drive
5. Space requirements
6. Noise levels
7. Operating temperature
8. Sufficient size to handle the required volume and pressure with minimum horsepower
9. Need for special coatings or construction when operating in corrosive atmospheres
10. Ability of fan to accommodate small changes in total pressure while maintaining the necessary air volume
11. Need for an outlet damper to control airflow during cold starts
We at SGM TECH provide all types of fans according to client's requirement. We appreciate your interest in fans and request the enquiry for the future transactions.
A MECHANICAL DUST COLLECTOR is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas. Designed to handle high-volume dust loads, a dust collector system consists of a blower, dust filter, a filter-cleaning system, and a dust receptacle or dust removal system.
Five main types of industrial dust collectors are:
1. Inertial separators
2. Fabric filters
3. Wet scrubbers
4. Unit collectors
5. Electrostatic precipitators
MULTIPLE CYCLONE DUST COLLECTORS :
Multiple-cyclone separators consist of a number of small-diameter cyclones, operating in parallel and having a common gas inlet and outlet, as shown in the figure, and operate on the same principle as single cyclone separators—creating an outer downward vortex and an ascending inner vortex.
MULTI CYCLONE DUST COLLECTOR removes more dust than single cyclone separators because the individual cyclones have a greater length and smaller diameter. The longer length provides longer residence time while the smaller diameter creates greater centrifugal force. These two factors result in better separation of dust particulates. The pressure drop of multiple-cyclone separators collectors is higher than that of single-cyclone separators, requiring more energy to clean the same amount of air. A single-chamber cyclone separator of the same volume is more economical, but doesn't remove as much dust.
We at SGM TECH design and manufacture all types of dust collectors. We use best engineering methods for optimum design and efficient performance along with top grade raw materials and modern technology to deliver the product on time and at best possible price. We also provide AUTOMATION on client's demand.
We also provide complete CUSTOM - BUILT, TURNKEY PROJECTS for ASH/DUST HANDLING SYSTEMS based on customer's process and requirements.

A RECUPERATOR is a special purpose counter-flow energy recovery AIR HEAT EXCHANGER positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat. Generally, they are used to extract heat from the exhaust and use it to preheat air entering the combustion system. In this way they use waste energy to heat the air, offsetting some of the fuel, and thereby improves the energy efficiency of the system as a whole.
SGM TECH designs and manufactures all types of RECUPERATORS. We adopt best design methods for efficient working and safety of the product. We provide conventional as well as custom built AIR RECUPERATORS and BOILER RECUPERATORS as our products. SGM TECH also provides high degree of AUTOMATION on client's demand.
