System and process for producing steam in a steam-hydrocarbon reforming facility where oxygen is removed from demineralized water using a membrane degasifier. The membrane degasifier operates at a lower temperature compared to a deaerator, which is the conventional technology for removing oxygen.

Powered and non-powered kits for the treatment of fluid in boiler and cooling systems, both open and closed recirculating are disclosed. The kits generally include a fluid container, a fluid connector configured to engage the fluid container, a hose configured for fluid communication with the fluid connector, a port, a fluid container suspension means, and a hose end support member. The fluid container is configured to enclose chemical agents and/or solutions. The port may be formed along the fluid container and be configured to receive the fluid connector. The hose end support member may support at least one portion of the hose at a desired height above the standing fluid to be treated. In embodiments, a metering pump is included with the kits, the metering pump configured to cause a predetermined amount of the chemical agents or solutions to be dispersed from the fluid container.

The present application relates to an exhaust steam waste heat recovering and supplying system used for air-cooling units in large thermal power plants. Each of the two steam turbines has independent exhaust steam extraction system, and the exhaust steam extraction system of each steam turbine is connected with corresponding pre-condenser to heat the return water of the heating network. The exhaust steam extraction system of each steam turbine is further connected with the corresponding steam ejector; the exhaust port of each steam is connected with the corresponding steam ejector condenser to heat the return water of the heating network. The exhaust steam waste heat of the air-cooling units in a thermal power plant can be recycled in high efficiency to improve the utility rate of the exhaust steam, increase heating capacity, reduce cold end loss to the largest extent, and maximize the energy saving benefits.
