    摘要： A process for preparing a coal-water fuel from a low rank coal. The first step of the process provides for an aqueous slurry containing particles of the low rank coal. A quantity of an agglomerating agent in the range of about 10% to 30% weight to dry ash - free low rank coal weight is added to the slurry to produce a mixture. The mixture is then agitated to form agglomerates. Following separation of the agglomerates, the agglomerates are contacted with steam or an inert gas having a temperature in the range of about 250.degree. C. to 420.degree. C. at substantially atmospheric pressure to produce partially deoiled agglomerates containing less than about 7% by weight of residual bridging liquid and having a moisture capacity reduced by a factor of at least about 2.5 at a relative humidity of 96% compared to the moisture capacity of the low rank coal. A first amount of the partially deoiled agglomerates is then first wet milled in the presence of water and at least one anionic dispersant, wherein the concentration of the first amount of the partially deoiled agglomerates in water is about 35% to 55% by weight, to produce a micronized fraction of the first amount of the partially deoiled agglomerates having a maximum size of about 15 to 25 micrometers and an average diameter of about 4 to 10 micrometers. Finally, a combination of the micronized fraction of the first amount of the partially deoiled agglomerates and a second amount of the partially deoiled agglomerates is final wet milled in the presence of water, wherein the combination is comprised of about 20% to 50% by weight of the micronized fraction, to produce the coal-water fuel which contains solid particles having a maximum size of about 250 to 300 micrometers and an average diameter of about 15 to 30 micrometers. In a further embodiment, the process utilizes a paste in place of the agglomerates, the paste being formed by mixing particles of the low rank coal with a quantity of a bridging liquid.

    摘要： The claimed invention relates to an heated clothing with autonomous heating source and comprise (a) thermally insulated suit adapted to cover the human body, (b) portable, low-temperature heat generation module with combustion process controlled by a control unit, c) infrared window for energy delivery, (d) heat energy distribution system to supply heat to different parts of the body, (e) temperature control system, including the temperature sensors, responsible for maintaining proper temperatures at different parts of the body and f) moisture adsorbing pads to remove excessive moisture originating from sweating. A light and flexible suit provides controllable stream of heat from a heater to a wearer for prolonged time. The suit includes attachable, heated gloves and boots and gives complete protection against even extreme cold. The invention can find application in the protection of people being exposed to cold environment, including construction workers, mineral exploration and oil field personnel, and other employees who's jobs require them to work at adverse weather conditions or those exposed to cold surroundings. It is also applicable for sport, pleasure and other recreational purposes. The heat generated by low-temperature heating unit, that is portable but located outside of the suit, is transferred to the interior of the suit via special window by means of infrared radiation. Infrared radiation energy is absorbed by the heat collecting plate and transferred inside of the suit to the different parts/regions of the human body by a heat distribution system. The control system module is equipped with temperature sensors, to measure temperature of different parts of the wearer's body, and provides for the control of stream of heat delivered to particular part of the body. The temperature of body parts is kept in the preset limits of temperature set individually by the suit user.

    摘要： A wall integrated thermal solar collector with heat storage capacity includes a transparent layer and a solar radiation absorption layer, that is separated by an air gap from the transparent layer. A heat storage layer of phase changing material is positioned in close contact with the solar radiation absorption layer to facilitate heat transfer. A structural panel of thermally insulating material is positioned adjacent to the heat storage layer.
