construction of energy-saving low nitrogen hot water boiler


Marine engines and auxiliary machinery - ScienceDirect

Jan 01, 2008 · Integrated energy-saving generating plants have been developed over the years by the major Japanese shipbuilding groups for application to large tankers and bulk carriers. The systems typically exploit waste heat (from low speed main engine exhaust gas, scavenge air and cooling water) to serve a steam turbo-alternator, air conditioning plant

Steam and Condensate - What is Steam and the properties of

Steam produced in any shell-type boiler, where the heat is supplied only to the water and where the steam remains in contact with the water surface, may typically contain around 5% water by mass. If the water content of the steam is 5‰ by mass, then the steam is said to be 95% dry and has a …

Waste to bioenergy: a review on the recent conversion

May 16, 2019 · The low carbon to nitrogen (C/N) ratio of microalgae biomass (from 4.16–7.82) also presents an issue for anaerobic digestion. If the C/N ratio is less than 20, a nutrient imbalance occurs in the anaerobic microbial community and causes the release of NH 3 as nitrogen waste.

Filtration - GVS Filter Technology

Hydrophilic – Hydrophobic Membranes. Hydrophilic membranes have permeability of aqueous solutions and once wetted, they stop gasses. This means that aqueous solutions pass through hydrophilic membranes but gas is stopped when the membrane is wet until the applied pressure exceeds the "bubble point", at which time the air will evacuate the pore, the liquid is expelled, and the gas will go

Chimney - Wikipedia

A chimney is an architectural ventilation structure made of masonry, clay or metal that isolates hot toxic exhaust gases or smoke produced by a boiler, stove, furnace, incinerator or fireplace from human living areas. Chimneys are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly, drawing air into the combustion in what is known as the stack, or

Journal of Advanced Research in Fluid Mechanics and

Abstract The combustion properties of torrefied mixture of empty fruit bunch (EFB) and polyethylene (PE) plastics were investigated experimentally, for weight ratio of 95:5 (EFB: PE) and 90:10. The mixture samples were obtained from briquettes that were produced under various briquetting temperatures (150°C-190°C). The torrefaction was performed at constant temperature of 250°C and at

Advanced Gas-cooled Reactor - Wikipedia

The Advanced Gas-cooled Reactor (AGR) is a type of nuclear reactor designed and operated in the United Kingdom. These are the second generation of British gas-cooled reactors, using graphite as the neutron moderator and carbon dioxide as coolant. They have been the backbone of the UK's nuclear power generation fleet since the 1980s.. The AGR was developed from the Magnox reactor, the UK's

Rotary Screw Air Compressors - Atlas Copco USA

Rotary screw air compressors are also available in two primary applications: oil free and oil injected. Here's a breakdown: Oil Free – External gears synchronize the position of the counter-rotating screw elements, and, because the rotors do not come in contact and create friction, no lubrication is needed within the compression chamber.As a result, the compressed air is oil-free.
