NISCO Fan Co. offers various designs of industrial fans and blowers for Pulp and Paper Industry.

The paper manufacturing industry utilizes fans for power boilers, recovery boilers, lime kilns, dissolving tanks, and dryers. These applications, which are integral to the production process, are often very corrosive. Reliability and durability of fans and blowers for such applications are vital for continuous operation. NISCO fans for demanding and corrosive applications ofer real value – saving on future downtime and maintenance costs.

BOILERS

Boiler fans create efficient combustion by supplying a consistent and reliable ait flow. Induce Draft Fans (I.D. Fans) operate at elevated temperatures and draw the air stream through the combustion chamber, then push it through pollution control equipment. Forced Draft (F.D. Fans) or Combustion Air Fans push the air stream into the boiler combustion chamber. Multi-Fuel Burning Power Boilers are used to create steam for different power needs. Induced Draft Fans are typically AMCA arrangement 3, single or double inlet with inlet box(es). Wheels often require abrasion resistant construction with radial tip or backwardly curved blades. Combustion Air FD Fans are typicallyconstructed of carbon steel, and utilize airfoil or backward inlined blade design. Common AMCA arrangements for combustion air fans are arrangement 3 and 8, both with inlet vane or outlet damper control.

EXHAUST FANS

Exhaust Fans are typically used on the suction side of a scrubber or fabric filter, and pull the air / gas stream through the piping and cleaning device. Dissolving tanks are used in conjunction with Recovery Boilers to recapture process chemicals. Exhaust Fans draw hydrogen sulfide or sulfuric acid fumes through a wet scrubber. This corrosive atmosphere can require either FRP, stainless steel or alloy construction. Exhaust fans can be in either belt or direct drive arrangements. Lime Kilns may be used to recover lime used in paper manufacturing. The fans used in this process often require high pressure and handle corrosive gas streams. Straight radial or radial tipped blade designs, 304L or 316L stainless steel construction and special shaft seals are often employed.

Oleg Systems Co. is a designer and manufacturer of industrial dust collection systems including dry type dust collectors. Dust collection equipment utilizing the principle of wet dust collecting is available in numerous designs utilizing a number of principles and featuring wide variation in effectiveness, initial cost, operating and maintenance expense, space, arrangements and material of construction.

The use of centrifugal force to throw a dust particle to the periphery of an air stream has been used in the cyclone collector for many years. Dry centrifugal dust collectors can be divided into two basic groups cataloged by their effectiveness in removal of smaller dust particles.

Cyclone Dust Collectors are frequently applied for the removal of coarse dusts from an air stream, as a pre-cleaner to more efficient dry or wet dust collectors and / or as a separator in product conveying systems using an air stream to transport material. Principle advantages are low cost, low maintenance and low pressure drop (in order 0.75″ to 1.5″ WG), but this type dust collector can not be used for collection of fine particles.

Life assurance, also known as life insurance, is a contract between the two parties, one the person who is to be insured and other the insurance company. According to this contract the insurance company will pay the beneficiary appointed by the insured in case of the death of the insured. Also in event of other problems like illness a smaller amount is paid by the insurance company. For getting this sum, insured person pays a fixed amount of instalments after a fixed time also known as premium. Life insurance can be divided into temporary insurance and permanent insurance. Temporary insurance is generally for only the death cases for a particular period with a fixed premium. Permanent life insurance is permanent in nature and cannot be cancelled by insurer unless there is some fraud committed in the application process. Permanent life insurance can be of many types like Whole life coverage, Accidental death insurance or limited pay insurance.

All other types of insurances, like property insurance, health insurance, accidental insurance, fall into the category of general insurance. When going for the property insurance you should always insure against the market value of the property, so that if at some point you have to make a claim then a fine is not imposed on you. When your property suffers some accidental damage and you are claiming insurance for it then you will be paid the insurance money only for the amount you have insured and for underinsuring you will have to bear half of the insurance money. In other cases like health insurance the insurance company will foot all of your hospital bills and you can pay the bills initially in either cash which will be reimbursed to you later or in a cashless way. General insurance for property or health are necessary for every home because you face such problems on day-to-day basis and it is better if you can save some money through these insurance policies.
