The boiler is important to the national economy electricity energy supply equipment, machinery, metallurgy, chemicals, textiles, paper, food and other industries, as well as industrial and civil heating boiler needs to supply large amounts of heat. Boilers using fuel combustion energy released or other energy to the working fluid (heat carrier intermediate) is heated to a certain device parameters. For heating the water to make it into the boiler steam is known as steam boilers, also known as a 50-500kg h capacity mini steam generator boiler for heating water to make them more water into the boiler temperature, known as the hot water boiler for heating of Heat Transfer Fluid It called boiler organic heat carrier boiler. From the energy point of view, the energy conversion device is a boiler. In a boiler, a chemical energy (fuel) storage by the combustion process into the combustion products (flue gases and ash) contained some heat, then the heat transfer process by transferring heat to the intermediate heat medium (e.g. water, and steam), it relies on the heat transport device to heat. This intermediate heating medium to transfer heat energy belonging to the second, because its purpose is to provide a device capable Into energy. When the intermediate heating medium for heat conversion in a thermal power machine, the work called quality. If only the intermediate transmission to the heating medium heating device to provide heat for heat utilization, is usually referred to as heating medium. It can be divided into four categories according to their use boiler power plant boilers, industrial boilers, marine boilers and locomotive boilers. The first two categories, also known as fixed boiler, because it is mounted on a fixed basis and immovable. The latter two are called mobile boiler. This book presents a stationary industrial boilers. The boiler in three main processes: (1) the fuel combustion in the furnace, which can be released in a chemical storage form of energy, the flame and products of combustion (flue gases and ash) having a high temperature. (2) high-temperature flame and smoke for heating the working fluid (heat medium) by heat transfer. (3) working fluid (heat medium) is heated to raise its temperature of vaporization or saturated steam, or further heated to become superheated steam. The above three processes are interrelated and simultaneously, to achieve the conversion and transfer energy. Along with the energy conversion and transfer of flow and also the changes of: (1) working fluid, for example water supply (or return> into the boiler, and finally reveal the form of steam (or hot water) (2) fuel, for example. combustion of coal into the furnace, which together with the combustion of the combustible portion of the original moisture content of the flue gas into which the original residual ash is ash-containing. (3) air into the furnace, wherein the combustion of oxygen to participate in the reaction, the reaction and the excess air the remaining inert gas is mixed in the flue gas is discharged. FAW water system, a coal ash smoking system is a system of wind two three main boiler system, the work of these three systems are performed simultaneously. this typically fuel and flue gas side process (involving the combustion, heat, slag, gas flow, etc.) collectively referred to as a furnace process; the process performed by water, steam which side -1 (steam and water flow, heat, vaporization, water separation, thermo-chemical processes, etc.) collectively referred to as the pot process. the main parameters of the boiler, the boiler comprising a heat generation quantity and quality indicators of both. as the main parameters of the number of steam boilers and steam production of the steam pressure, temperature, water the main parameters of the boiler Hot water flow rate and pressure of hot water temperature.
As a top steam boiler manufacturer in China, ZG Boiler has been a premier provider of high-pressure industrial gas fired steam boilers for the industrial laundry markets for over 70 years. Our durable and simple horizontal design is a perfect fit for large industrial laundries factory. Because large size industrial laundries also utilize gas fired steam boilers to provide heat to the ironers, heated rolls, hot water storage tanks, and to provide steam using an unfired steam generator. Large industrial laundries are common in healthcare facilities, resorts, high-end hotels, and prisons.
What is boilers is an energy conversion device, the energy input to the boiler chemical energy, electrical energy, a boiler output of the fuel has a certain thermal energy of steam, hot water or organic heat carrier. The original meaning refers to the pot on the fire heated containers that hold water heater which places combustion of the fuel, boiler and furnace boiler consists of two parts. Generating hot water or steam boiler may directly provide the necessary heat for industrial production and the people's life, by a steam power plant can be converted into mechanical energy, or through the generator converts the mechanical energy to electrical energy. Provide hot water boiler hot water boiler is called, is mainly used for domestic, industrial production also have a small application. Boiler steam is known as steam boilers, often referred to as boiler, used for power plant, ships, locomotives, and industrial and mining enterprises.
20th Meeting of the Standing Committee of People's Congress of the fourth Jinzhong City, approved the Thirteenth People's Congress Standing Committee of Shanxi Province, the seventh meeting since January 1, 2019 the formal implementation of the "Jinzhong City coal pollution prevention and control regulations "(the" Ordinance ").
1, Municipal People's Government shall determine the total amount of coal required control objectives, the development of coal-fired reduction and clean energy transformation plan and organize the implementation, reduce the proportion of coal in primary energy consumption structure in accordance with the requirements of the provincial government and city environmental protection.
2, Municipal People's Government shall designate built-up area for the city ban on coal zone and gradually extended to improve the quality of atmospheric environment on request. Counties (cities, districts) need to improve the people's government should ban on coal zone demarcated according to the ambient air quality.
May, ban coal-fired power plant area, central heating stations and raw coal units shall establish a coal purchase and sale of its products archives management, and self-purchase contract is signed or change within fifteen days, the number of coal procurement and information submitted to the seat of county government department in charge of energy.
6, city and county (city, district) people's government should promote the local conditions of the administrative regions of central heating, coal to electricity, coal gas and other clean energy alternative to coal-fired work. Encourage towns, rural areas to promote the use of clean energy living stove.
9, city and county (city, district) people's government should strengthen the management of civil bulk coal regions other than coal ban areas, to determine the clean coal supply companies, establish and improve civil cleaner fuels coal procurement, storage, supply mechanism to protect the clean coal supply.
10, city and county (city, district) people's government market supervision and management departments should be included in the annual coal-fired coal sampling plans to strengthen quality supervision and inspection, and to the public inspection results.
11, coal-fired power plants, district heating stations and boiler units to use raw coal output and single kiln production process should be in line with national standards and local regulations or policies. Any unit or individual may manufacture, import, sale and use do not meet environmental protection standards of boilers, furnaces.
12, supporting the construction of coal-fired units should use air pollution control equipment and facilities to maintain normal and stable operation, pollutant discharge should meet the standards set by the state and local levels. Encourage the use of coal-fired units to implement ultra-low emissions transformation in accordance with the requirements of environmental protection.
