What is a heating plant?
Heating equipment concerns a steam or hot water heating system that serves a number of outlying buildings. It is specified according to the type of device used. The device consists of a boiler; pumps; valves; steam water pipeline; and storage, handling and feed system feed. Key components of the heating equipment include operating conditions, type of boilers and fuel source.
Toper rooms are common among older university campuses, rural or outside industrial sites and military complexes. These devices are often placed together with electric city or industrial tools. Shared use is common between processing plants that use a high -pressure pair, and then pass on a low -pressure pair to a hospital or college to use the heat rather than drain them into the environment through a cooling tower or a cooling pond. The space in which a small boiler is located in the basement of one building is usually referred to as a boiler room, as the opposed toTop plants.
Capacity and operating pressure and temperature are key design issues determined by the expected thermal load. To avoid complete outage, the heating equipment usually has two or three boilers. The steam pressures are usually limited to less than 150 PSIG (1035 kPa). The typical operating range is from 100 to 125 PSIG (690 to 862 kPa), but the most economical design will consider higher costs of a higher pressure system compared to the operating load required to warm up buildings.
The construction of the water tube is often used for boilers used in heating plants. In this design, hot gases from fuel burning pass through pairs generating tubes in which the water from the drum on the feed heats up on the boiling. The steam rises to the steam separation drum, where condensed water flows through gravity through large tubes, called downcomers back to the water drum to preheat it. Further energy is added toCouples over the boiling point by drawing steam from the steam separation drum back through the hot gas chamber again.
The boiler can be driven from various sources, including gas, coal or other fossil fuel. Many renewable sources are also used, including geothermal heat, wood, city waste or agricultural biomass. The energy source is selected on the basis of the availability, costs and thermal load requirements. If the high -energy fuel source and thermal load are relatively low, the electricity cogeneration from the side of the steam passing through the turbine is possible. The heating equipment that uses a line of waste steam line from a high -pressure steam source can use a restarter to strengthen the incoming steam heating value or can easily be consisted of a distribution system.
