department of boiler bangladesh address
Also, if used improperly will play a scale inhibitor for the protection of the department of boiler bangladesh address opposite effect, accelerate the scaling and corrosion of boilers, to the normal operation of the boiler poses a serious threat. 03, did not pay attention to the pH of the boiler water:
Why do gas-fired steam department of boiler bangladesh addresss require high water quality?
Many boiler users know that when buying a boiler, the boiler manufacturer's technicians will repeatedly explain the requirements for the boiler water quality. This is because the boiler water quality is a prerequisite for the normal operation of the steam boiler. Correct and reasonable water treatment can be used. Avoid the scaling and corrosion of gas boilers, extend the service life of boilers, reduce energy consumption, and improve the economic benefits of enterprises. Today we will talk about the impact of water quality on natural gas steam boilers.
Installation of fuel gas-fired department of boiler bangladesh address safety valve safety valve is one of the important requirements of the protection device fuel gas-fired boiler, boiler user is necessary for proper installation of the safety valve. Following small talk to the fuel gas boiler safety valve installation points: (1) greater than the rated 0.5t h fuel gas boiler / evaporator, at least two safety valves installed; equal to or less than the rated evaporation 0.5t / h fuel gas-fired boiler, at least install a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. (2) safety valve should be mounted vertically at the highest position boiler drum, collection tank. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. (3) have lever-type safety valve means for preventing movement of the self-weight and deviant restriction lever guides the spring loaded safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. (4) The rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. (5) safety valve boiler tubes, which cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, short tube passage area not less than 1.25 times the area of all the exhaust valve. (6) safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
A few days ago, Datong City, Shanxi Province, issued a "decisive battle 300 days, to enhance the" Datong blue "plan", combined with ongoing Shanxi Province: innovation, work for "the great debate, promote green development, and constantly improve the level of ecological civilization, achieve a good number of days 300 days throughout the year for more than two goals. details are as follows.
1, aspects of the transition. On the basis of the regulation last year, continued to carry out "dirty scattered" enterprise rectification work. According to industrial policy, industrial layout planning, as well as land, environmental protection, quality, safety, energy consumption, etc., to carry out an intensive investigation, the establishment of management accounting. In accordance with the principle of "first stop after the rule", the implementation of classification disposal, have been banned "dirty messy" business, appears to prevent the resurgence of the phenomenon.
2, corporate governance aspects. Industrial pollution discharge standards to strengthen the comprehensive management of enterprises can not achieve full compliance, should be taken to stop production remediation. Full completion of key industries pollution remediation work, on the basis of the city's nine power companies that run on ultra-low emissions stable, GD Datong Power Generation Co. Ltd. within the scope of the built-up area of the city and Datang International Yungang Thermal Power Co., Ltd. completed before the end of the colored Amidst the governance feasibility report, we lay the foundation for next year colored misty rain governance. December 30, 2019, to carry out ultra-low emissions and chemical industry, iron and steel, nonferrous metals, cement industry, especially emission limits transformation; completed 100 industrial enterprises fugitive emissions control, industrial furnace control 41 upgrades, 11 key industries and enterprises volatile organic compounds governance and four key industries and enterprises volatile organics management upgrade.
3, less coal ways. Insist on proceeding from reality, should be in accordance with the electric power, gas should the gas, should the coal coal (ultra low emission), should be hot is hot, and more heating energy policy to ensure the safety of the masses warm winter. Residents living coal simultaneous implementation of clean energy alternatives. District heating flat built-up area clean 100% coverage, coverage of other counties clean heating built-up area of more than 70%, 40% or more in rural areas, to proceed with the phase-out of coal-fired boilers. Renovation project to carry out ultra-low emission coal-fired boilers, October 1, 2019, 65 tons of steam coal and above and build the region (biomass) and energy-efficient boilers to complete the transformation of ultra-low emissions, low nitrogen gas boiler basically completed the transformation.
