| The present invention relates to a sauna bathroom. At present, a commercial sauna bathroom is generally provided with apparatus both for shower-bath and pool-bath. With plenty of hot water drained in vain, a sauna bathroom is often gloomy and damp. To take a bath at home, no matter it is a tub bath, a shower bath or a shower bath using a water heater, often involves high costs and is cold in cold weather. For a shower bathroom type or suspended sauna bathroom or a commercial sauna bathroom with steam, there is only one outlet for the steam to enter into the sauna bathroom, thus forming a steam column rising upward after the steam comes out off the outlet. Therefore, the upper part is too hot and stuffy, while at the lower part it is cold. In order to overcome the above-mentioned various difficulties, the present invention involves a plurality of outlets provided around the lower end of the bathroom for steam entering into different types of sauna bathrooms. Means for supplying the fresh air or hot air is arranged in the same height as of a washbasin so that a user does not feel stuffy in the bathroom. The present invention also provides a minisize sauna bathroom and enables wet sauna to be offered as the only way of bathing in a commercial sauna bathroom into which hot water, hot air and steam are supplied. | ||||||

| 210 | Heating furnace for recovery of energy from compacted paper, straw and like fuels | US852959 | 1986-05-01 | US4732090A | 1988-03-22 | Heinrich Bollmann, Sr.; Heinrich Bollmann, Jr. |
| Heating boiler intended to be used for burning straw, paper and similar fuel material in the form of compressed bales. The boiler is capable of supplying the material to be burned as a function of the heat requirements. It is necessary to provide optimum combustion conditions to maintain exhaust gas emission values within prescribed limits. The boiler is therefore provided inside its combustion compartment with a channel (2) wherein the compressed bales are dried and the slow distillation gas is removed to a large extent from the fuel. The bale supply channel (2) opens into a combustion chamber (4) enclosing the combustion compartment and preventing the flames from touching the water jacket (15) of the boiler. | ||||||
| 211 | Biomass-fueled furnace | US616902 | 1984-06-04 | US4559882A | 1985-12-24 | Lawrence A. Dobson |
| A combustion system for domestic or small industrial heating needs, utilizing biomass fuels such as wood and brush chips, sawdust, logs, nut hulls, peat, leaves and other organic waste products of forestry, agriculture and industry with essentially smokeless, clean exhaust. By preheating the combustion air, insulating the combustion process and carefully controlling the fuel to air proportions and mixing parameters, essentially complete combustion with very little excess air at high temperatures is achieved even with fuels containing over half their weight in water. This water is then condensed out of the exhaust gases in uniquely designed air and water counterflow heat exchangers that can capture over 90% of the high heat value of the fuel. This invention is capable of maintaining clean combustion at high temperatures with little excess air, at burn rates much lower than the best popular "air-tight" woodstoves and is capable of higher heat outputs than most domestic heat plants. This biomass-fueled furnace does not require electric fans or controls and can be used where electricity is unavailable. | ||||||
| 212 | Combination wood-fired boiler and storage apparatus | US480922 | 1983-03-31 | US4549526A | 1985-10-29 | Martin R. Lunde |
| The application discloses improvements in a combination solid-fuel-burning, liquid heating and thermal energy storage apparatus in which a firebox is immersed in a large tank for heating the liquid stored therein and in which an improved flue assembly carries gaseous combustion products from the firebox through the tank liquid to an exhaust stack which has an outlet outside the tank. A blower draws combustion air into the firebox, draws the resulting gaseous combustion products through the flue assembly and provides a forced discharge of said combustion products through the stack outlet. The blower preferably includes a rotary fan in a fan housing which is serially connected in the flue assembly and positioned within the liquid inside the tank to provide a heat exchange housing enhancing the transfer of thermal energy from the combustion products to the surrounding tank liquid and minimizing possible high temperature damage to and excessive wear of the blower parts. Other improvements in the flue assembly members, the constantly open venting means, the firebox construction and other parts of the apparatus are also disclosed. | ||||||

| 218 | Hot water boiler | US926401 | 1978-07-20 | US4231350A | 1980-11-04 | Dean E. Marsh |
| A hot water boiler having a dual combustion chamber arrangement capable of burning either solid or fluid fuels, and arranged for acting directly on a heat transfer system generally in direct contact with firebox walls of the combustion chamber arrangement. Disposed atop the combustion chamber arrangement is a heat conserving flue assembly which absorbs heat from smoke and flue gases exhausted from the combustion chamber arrangement and heats a fluid medium which in turn is circulated to the heat transfer means for eventual release for circulation or storage as desired in a residence or other building structure. The heat transfer system includes a fluid containing cavity divided into two parts by a suitable membrane, with pipes being provided penetrating the membrane for permitting transfer of the fluid medium from one part of the cavity to the other, with the heat transfer fluid medium thus being initially heated in the flue assembly, transferred to a first, or uppermost, part of the cavity of the heat transfer system, and subsequently transferred to the lower part of the heat transfer system and discharged entirely from the boiler structure. | ||||||
| 219 | Apparatus for heating a heat transfer fluid protected against overheating | US709098 | 1976-07-27 | US4044727A | 1977-08-30 | Niklaus Rychen; Peter Werner Fuchshuber |
| In an apparatus for heating a heat transfer fluid flowing through concentrically arranged pipe coils in a boiler casing, the casing is supported on top of a furnace in which solid fuel is burned in the combustion chamber. The combustion gases flow directly from the combustion chamber into the boiler casing for passage over the pipe coils. Solid fuel is supplied by a conveyer into a grate below the combustion chamber and air is supplied to a primary combustion air chamber and a secondary combustion air chamber for flow into the combustion chamber. The heat transfer fluid is circulated through the pipe coils by a pump and, if the pump becomes inoperative or flow otherwise stops, the supply of fuel and air is automatically discontinued to avoid overheating of the heat transfer fluid. | ||||||
