chemistry of low pressure boiler power plant

Steam chemistry of low pressure boiler power plant can learn more about the problem by what? In a steam boiler, it uses induced draft fan, if the model is Y5-47-4, then, what the specific meaning? Steam boiler condensate tank, you can play what role? And, on steam boilers, as well as what issues were not resolved? Raised above problems, and its main purpose is to be successfully resolved, thus, increase the level of understanding of people know this kind of boiler steam boiler. 1. Steam Boiler Fan model Y5-47-4, indicates what? Steam Boiler Fan model, the model is Y5-47-4, then you can know is: Y is a fan guide, and if G, is for the blower. Figures 5, refers to the pressure coefficient, which illustrate a pressure fan. 47, it refers to the ratio of the fan speed. 4 later, it indicates that the fan impeller diameter of 4 centimeters.

Operational efficiency and the use of chemistry of low pressure boiler power plant efficiency condensing gas factors affecting brewery brewery condensing gas boiler length of time is important reference customer choice and purchase of the boiler. Of course, this is a preliminary issue, linked to the quality of the boiler, but after the operation and maintenance of the real needs of customers insist on a regular basis to complete. 1. The difference between the mass of gas and liquefied petroleum gas is a relatively pure source of gas, the gas is relatively poor artificial, impurities inside thereof, an unstable component, a low calorific value, the greater impact on the life of the equipment. 2. WATER QUALITY China's large land area, large differences in water quality. Water calcium and magnesium ions of different contents. Condensing boiler water treatment even after softening, easy to scale, but only to soften the water to reduce the content of calcium and magnesium ions, can not be completely eliminated. The results show that the heat transfer performance of the system deteriorates to reduce the diameter, the flow is blocked, the energy consumption increases. Gas boiler condensate pump clogging once the flow is not smooth, easy to failure, damage to the main heat exchanger at high temperature easily. Thus greatly reducing the time used in boiler water circulation system equipment. The quality of steam produced is also not high.

When the chemistry of low pressure boiler power plant water filling, why should the provisions of Sheung Shui Sheung Shui temperature and time required? Operating procedures and boiler temperature of Sheung Shui Sheung Shui time are clearly defined, mainly consider the safety of the drum. Sheung cold furnace, the drum wall temperature equal to the ambient air temperature, when the feed water through the economizer into the drum, the drum inner wall temperature increased rapidly, and the temperature of the outer wall to the outer wall with the heat transmitted from the inner wall gradually increases . Since the thick-walled drum (pressure in the furnace is 45 ~ 50mm, autoclaves of 90 ~ 100mm), an outer wall temperature rises slowly. The inner wall of the drum has a high temperature expansion trend, while the outer wall temperature is low, to prevent the inner wall of the drum expansion. Compressive stress so that the inner wall of drum, and an outer wall subjected to tensile stress, so that thermal stress generated drum. Thermal stresses and the size depends on the thickness of the inner and outer walls of the drum wall temperature difference, the temperature difference between the inner and outer walls and in turn depends on the temperature Sheung Sheung speed. Of water on a high temperature, Sheung fast speed, the thermal stress is large; the contrary, the thermal stress is small. As long as the thermal stress is not larger than a certain value is permitted.

Jiamusi City, Heilongjiang Province Tangyuan county government to further implement the "Heilongjiang Provincial People's Government of Heilongjiang Province on the issuance of three-year action plan to win the notice of blue sky Wars," the actual situation, carry out a comprehensive rectification for small coal-fired chemistry of low pressure boiler power plants, as follows .

First, the objectives

By the end of 2019 out of the region to build 26 units per hour and 10 tons of steam coal-fired boilers and furnaces tea, operating a stove, food equipment and other coal-fired kiln drying facilities. Out of which 14 coal-fired heating boilers Small units, service three coal-fired boilers, industrial production of small coal-fired boilers nine. By the end of 2020, the region will build small coal-fired boilers cleared number, and completed more than 10 tons of steam per hour of coal-fired small boilers governance standards.

Second, the specific content of execution

1, source control. County-level cities built in the region 35 tons of steam per hour ban on new coal-fired boilers, the rest of 10 tons of steam per hour ban on new coal-fired boilers and below.

2, find out the base. Focus on carefully checking the area of ​​coal-fired boilers case, before the end of May, the completion of the area and the development of coal-fired boilers ledger built-up area, and clearly out of all kinds of coal-fired boilers responsible departments and completion time.

3, held a mobilization meeting. 10 tons of steam per hour, organization and small coal-fired boiler unit, responsible departments held a meeting to clear out of time limits, and invite gas companies, boiler manufacturers, heating companies and small boiler unit for docking, to help provide alternative solutions Program.

4, announced the phase-out plan. Through government websites, issued to small coal-fired boiler unit a variety of ways such as notification, publish small coal-fired boilers out of the list, time frame for completion and telephone hotlines.

5, to carry out law enforcement inspection. Organization of joint law enforcement inspection, supervision of small coal-fired boiler unit to carry out the planned phase-out time frame. Carried out errant time, press the "Heilongjiang Province Air Pollution Prevention Act," the imposition of penalties.
