Abstract: A system for utilizing a fuel having a high ash content, water content in excess of 50% and large particles of combustibles is shown which includes a holding tank for the fuel. Fuel is circulated in the holding tank to maintain the consistency of the fuel and a metered portion is removed, strained and fed to a combustion device. The combustion device is a fire tube boiler for generating steam and includes a furnace tube insulated with refractory material extending for its entire length. The system mixes a preselected amount of atomized fuel with combustion air and natural gas. Special ash and particulate accumulation means are provided in the boiler. The boiler also has a water spraying system in its combustion chamber to reduce combustion temperature and increases water content of the combustion mixture based on the temperature of the combustion gases at the end of the furnace tube. Finally, when the boiler is shut off, the entire system, including a bypass system, may be purged by air or water.

Abstract: A unit combining a diaper dispenser and disposal drawer is shown. The unit consists of two sections, an upper dispensing section and a lower disposal section, which provide a single unit for new and soiled diapers, as well as other supplies used in changing a baby. The upper dispensing section has a number of dividers which define vertical shafts. Diapers are placed in these shafts and are removable at the bottom thereof through adjustable slots. The slots of the upper dispensing section are adjustable by using a removable shelf. The vertical shafts are also adjustable in cross-sectional size to accomodate different sized diapers. A slidable front panel permits easy access to one or more of the vertical shafts for reloading. The bottom disposal section comprises a cabinet generally rectangular in shape with a pivoting, top-opening door. This disposal section may contain a separate bin, such as a plastic bag or bucket which is easily removed to dispose of soiled diapers and other waste.
