摘要： An economizer having a structure capable of efficiently warming water and facilitating inspection and cleaning is obtained.
In an economizer for warming water by combustion exhaust gas generated by a boiler, to a cylindrical water pipe in which an inflow port and an outflow port are formed on a side surface and through which the water passes, a plurality of gas pipes erected for circulating the combustion exhaust gas are arranged in corresponding fan-shaped portions of the water pipe. The combustion exhaust gas introduced from a bottom surface side of the water pipe folds back at an upper part of the water pipe and flows downward, then folds back at a lower part of the water pipe, flows upward, and flows out from an upper surface side of the water pipe, whereby the plurality of gas pipes efficiently warms the water in the water pipe.-

摘要： A system for generating high pressure steam from dirty water uses a combination of submerged plasma arcs and electrical resistive heating. Dirty water from steam assisted gravity drainage, or other dirty water producing process. Which needs to be converted into high pressure steam, is fed directly without any pre-treatment, into a plasma fired steam generator, powered by submerged electrodes. The combination of electric arc plasma and resistive heating is created between the submerged electrodes. The heat so generated will boil the water portion of the dirty water feed to generate steam that is collected in a steam space and then removed therefrom. The solids and other residues (residual sludge) present in the feed water settle down at the bottom of the steam generator and are removed via a blow-down stream. The plasma arcs are used to intermittently remove any scaling or solid deposits that can accumulate on the electrodes.

摘要： The present application relates to a system for generating steam, the system (1) comprising: a wall structure (3) forming a steam chamber (3A); an opening (4) formed in a wall portion (3B) of said wall structure (3); and a cover member (5) cooperating with said wall portion (3B) such that the cover member (5) can take a first position (P1) where the cover member (5) covers the opening (4) and a second position (P2) where the cover member (5) uncovers the opening (4); wherein said opening (4) has a cross-section surface being at least 50% of the cross-section surface of said wall portion (3B). The invention allows easy access to an inside part of the steam chamber (3A), thanks to the opening (4) provided in the wall portion (3B) of the steam chamber (3A), so that the user of the system (1) can clean the inside part of the steam chamber (3A) of scale.

摘要： A method and apparatus for direct contact steam generation for a variety of industrial processes including heavy oil recovery, power generation and pulp and paper applications. The steam generation system consists of a combustor (10) and a steam generator (70) and is constructed to be operable at elevated pressures. The fuel, at least one oxidant and a fluid supply including water are supplied at pressure to the combustor. Flue gas from the combustor (10) is delivered to the direct contact steam generator (70) at pressure, and upon direct contact with water, produces a flue gas stream consisting primarily of steam. This product stream can then be cleansed and used for industrial applications. The combustor (10) can be operated with low grade fuel and low quality water with high solids and hydrocarbon contents. The apparatus and method reduce the environmental footprint by reducing air emission, concentrating CO2 to enable capture and reducing clean water requirements. The removal of solids from the combustor (10) at its second end (62) as well as at the second end of the steam generator (70) as at (78), the use of water injection-type steam quality control and a steam feedback inlet (46) to the combustor (10) from the steam generator (70) enhance the efficiency of the apparatus.

摘要： A boiler that includes a housing is disclosed. The housing houses a combustion chamber, a heat exchanger system, a heat flow path, an isolating member, and a removable panel. The heat flow path thermally couples the combustion chamber and the heat exchanger system. The isolating member at least partially separates the combustion chamber from the heat exchanger system wherein. When the removable panel is removed a user is provided access to the heat exchanger system. The isolating member is internal to the housing. The removable panel is an internal removable panel positioned on the isolating member. When the internal removable panel is removed, the user is provided internal access to the heat exchanger system. In other embodiments, the panel is an external removable panel positioned on an exterior wall of the housing. When the exterior removable panel is removed, the user is provided exterior access to the heat exchanger system.

摘要： A system for generating high pressure steam from dirty water uses a combination of sub-merged plasma arcs and electrical resistive heating. Dirty water from steam assisted gravity drainage, or other dirty water producing process, which needs to be converted into high pressure steam, is fed directly without any pre-treatment, into a plasma fired steam generator, powered by submerged electrodes. The combination of electric arc plasma and resistive heating is created between the submerged electrodes. The heat so generated will boil the water portion of the dirty water feed to generate steam that is collected in a steam space and then removed therefrom. The solids and other residues (residual sludge) present in the feed water settle down at the bottom of the steam generator and are removed via a blow-down stream. The plasma arcs are used to intermittently remove any scaling or solid deposits that can accumulate on the electrodes.
