D type water tube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or “mud drum”) at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam). These are surrounded by walls made up of larger water-filled tubes, which make up the furnace.
After opening the about boiler in tnpl winter operation, we can see a lot of red fluffy black slag deposited on the bottom of the drum and the collection box, also seen in the sheet-like water residue adhered drum, water wall tubes and smoke collector the inner wall of the box.
2. szl series chain grate about boiler in tnpl
The boiler body is composed of a vertical upper and lower drum and a convection tube bundle, and a water-cooled wall tube is arranged in the combustion chamber, and a pot-and-gas device such as steam-water separation and continuous sewage discharge is arranged in the upper drum, and a regular sewage device is arranged in the lower drum, and the tail portion is arranged There is an economizer (air preheater), the furnace arch is made of refractory clay bricks, and the outside of the boiler main body is a three-dimensional shield shell. The szl series boiler is a coal-fired biomass water tube boiler.
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.
