Boiler equipment includes: a combustion device including a combustion chamber to combust fuel supplied to the combustion device; a combustion furnace including a combustion chamber formed inside thereof; and a heat exchanger transferring thermal energy obtained by combustion of the fuel in the combustion device to water. The combustion device is directly connected to a wall part of the combustion furnace such that the combustion chamber of the combustion device faces the combustion chamber of the combustion furnace. The fuel is efficiently combusted in the combustion chambers of the combustion device and the combustion furnace, which are integrated with each other. Thus, almost no ash is generated.

A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic material is pulverized to a particle size of less than about 2 mm. The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying of the high protein organic waste material within the combustion chamber. Temperature and nitrogenous hydrocarbon combustion reactions within the combustion chamber are also controlled by injection of steam within the combustion chamber. The concentration of protein thermal decomposition by-products, the temperature and/or pressure within the combustion chamber is also controlled to degrade hazardous polyfluoro compounds into less hazardous compounds.

At least one aspect of the technology provides a self-contained processing facility configured to convert organic, high water-content waste, such as fecal sludge and garbage, into electricity while also generating and collecting potable water.

A method for reducing the emission of contaminants by a furnace is provided. The method includes forming a bed from a stream of fuel within the furnace; fluidizing the bed with flue gas from the furnace; and heating the fuel within the bed so as to generate char, ash and contaminants. The method further includes capturing the contaminants via the ash.

A waste burning toilet may operate on power generated from burning waste deposited in the toilet without connection to external electricity, a sewer, or water supply. A dryer connected to the toiled dries the waste prior to burning. The waste may be burnt in a firebox that is connected to the dryer. Heat from the firebox may be used to generate electricity that can power the components of the toilet system. The waste may be reduced to sterile ash.

Systems and processes provide for a thermal process to transform sludge (and a variety of other natural waste materials) into electricity. Dewatered sludge and other materials containing a high amount of latent energy are dried into a powdered biofuel using a drying gas produced in the system. The drying gas is recirculated and is heated by the biofuel produced in the system, waste heat (from turbines or internal combustion engines), gas (including natural gas or digester gas) and/or oil. The biofuel is combusted in a boiler system that utilizes a burner operable to burn biofuel and produce heat utilized in a series of heat exchangers that heat the recirculating drying air and steam that powers the turbines for electricity production.
