However, water-tube power plants in bin qasim pakistan boilers are also manufactured in sizes to compete with shell boilers.

Small water-tube boilers may be manufactured and assembled into a single unit, just like packaged shell boilers, whereas large units are usually manufactured in sections for assembly on site.

What should pay attention to the power plants in bin qasim pakistan boiler hot start? (L) Unit hot start, if the boiler is cold, the boiler should start operating program parameters cold start sliding manner. (2) a hot start, the steam turbine main steam parameters required turn red at a temperature greater than the high pressure cylinder inner wall temperature of 50 ℃, and there are 50 deg.] C superheat, but considering the safety apparatus to the boiler, a main steam temperature should be below the rated steam temperature value 50 ~ 60 ℃. (3) unit starts, if the boiler pressure should only after the ignition is turned on in a secondary, or bypass and valve to the air exhaust. (4) reheat steam inlet steam temperature should not exceed 400 ℃ :, if a bypass desuperheating water can not put into use, the main steam temperature not higher than 450 ℃. (5) due to the high hot start parameters, should be increased steam flow through, to avoid overheating the wall, adjust combustion.

Phase out coal-fired power plants in bin qasim pakistan boilers, promote air pollution control is an important measure to improve the air quality of the environment. Zhangjiakou City, Hebei Province, according to the central and provincial government deployment requirements, in-depth launched out of control for coal-fired boilers, and comprehensively promote the city's 35 tons of steam / coal-fired boiler sales and less "clear" work to ensure the city's air quality improved and enhanced.

The phase-out of coal-fired boiler from the following three points.

First, the coal-fired boilers carry out a comprehensive investigation work.

Depth investigation and the remodeling phase out coal-fired boilers and "coal to electricity", "coal to gas" and so on, electricity consumption by verifying the number of boilers and eliminated the need for the transformation of gas to develop a control list in 2018 coal-fired boilers to natural gas, electricity security for the ability to determine the "coal to electricity", the number of "coal to gas," the boiler. Do a boiler in a table, as well as finishing the complete elimination of the transformation of the way, rectification, acceptance, responsibility for people's list, to lay the foundation for the next phase out coal-fired boilers governance.

Second, carry out the phase-out coal-fired boilers.

Carry out a comprehensive phase-out 35 tons of steam / hour and below the coal-fired boiler, stove, operating a small coal stove, the main urban built-up areas and the urban fringe, and built-up areas within the county Economic Development Zone range, a ban on new coal-fired boilers other regional ban on new 35 steam tons / hour and below the coal-fired boilers. For central heating central heating in the official website of the area covered, when not incorporated central heating, heating mode using a variety of propulsion power, natural gas, industrial waste heat utilization, and energy from the source to control pollution.

Third, strongly promote the boiler-depth treatment.

Focus on pollution control bulk coal, comprehensive transformation of the use of coal boilers and generators. Stoker addition, stoker furnace, over the remaining 65 tons of steam / h coal-fired boiler to complete the transformation process ultra-low emissions, the city above 35 t steam / hour is then mounted boiler line monitoring devices, and environmental protection authorities and networking, production facilities and quality facilities simultaneously, real-time monitoring.

2. the countermeasures 1. Increase supervision of power plants in bin qasim pakistan boiler water treatment

Company management personnel should pay attention to the supervision of boiler water work, and give full play to the functions of supervisors, and promote the staff to pay attention to boiler water treatment work from the ideology. In addition, the supervisors should also put forward detailed boiler water treatment policies, and conduct inspections on time, urging them to change their working attitudes, advance the quality of work, and then ensure the smooth opening of boiler water treatment work.

2. Choose a reasonable boiler water treatment method: In industrial production, the quality of boiler water varies from company to company because of the nature of the company. To advance the professional skills of boiler water treatment, its primary task is to strengthen the staff's knowledge of the boiler water properties, including the composition of the boiler water quality, pH, hardness and so on. In this way, the staff can use different treatment methods for different types of boiler water in the internship work to ensure the safety of the boiler.
