Abstract:

A zeolite based SCR catalyst for NOx reduction using a reducing agent for treating exhaust streams from industrial and commercial boilers is provided. The reactor system has a zeolite based catalyst arranged in catalyst cassettes in a modular fashion where the reactor containing the zeolite based SCR catalyst cassettes is placed in a perpendicular direction to the exhaust exiting the industrial and/or commercial boiler. The catalyst selectively reduces nitrogen oxides to nitrogen with a reducing agent at low to medium temperatures. The reactor results in high NOx conversions and very low ammonia slip and is active for a wide range of boiler firing conditions. Boilers with low NOx and/or ultra low NOx burners can be replaced with a standard conventional burner for overall emissions reduction performance, efficiency improvements and energy savings. Boilers with low NOx and ultra low NOx burners can also be fitted with this zeolite based SCR catalyst reactor for additional NOx reductions and energy savings.

Abstract:

An Improved Surfboard Rack is disclosed. The disclosed surfboard rack comprises one or more rack units, to be attached to a substantially vertical surface and separated from each other by a preferred distance "X", depending upon the particular application for the rack. As disclosed the preferred rack unit comprises a base from which protrudes at least one strut member, and with said rack unit may further including a strut retaining portion, attached to the base, and from which each said strut member protrudes. Each disclosed strut member is preferrably canted upwardly from 4 to 20 degrees above horizontal. Also disclosed are strut members that may be permanently or removeably attached to said base and/or strut retaining portion. The disclosed strut members preferrably comprise a rigid core having a cap and a sheath of rope, foam rubber or other material thereover. The preferred base and strut retaining portion could be formed from wood, plastic or other substantially rigid material.
