China Water Tube Steam Boiler

China Water Tube Steam Boiler

How to determine the china water tube steam boiler water accidents have occurred when the water level had the lowest water level is less than identity, but can still be seen when the water level in the water level, sentenced to mild water; when the water meter can not see the water level, ruled severe water shortages. The finishing state include the following: a conventional water level (1) is less than the height of drum level identifier; (2) low level alarm, automatic warning sounds, warning lights light; (3) the temperature of the superheated steam vapor is increased; (4) providing the amount of water is not a conventional, less steam flow; (5) the temperature of the exhaust gas water vapor increases.

Step 1 boiler pressure test, pressure test should be carried out when the ambient temperature is higher than 5 ℃, antifreeze measures must be below 5 ℃, water pressure test should be maintained above the dew point of the ambient temperature to prevent boiler surface condensation, water seepage and the occurrence of the situation will not tight confusion, difficulty increases inspection; but it should not cause high temperature to prevent vaporization (so difficult to find the leak) and excessive temperature stress, usually 20 ℃ ~ 70 ℃. 2, after the water is full, pressure is gradually increased to 0.4MPa, namely a tight check, if necessary, be tightened once the flange, and hand Manhole cover bolt hole. 3, water pressure test, pressure should slow down, when the pressure rises to the pressure of work, should be suspended boost, check for leaks or anomalies, and then boosted to the test pressure for 20 minutes, if the pressure It did not decline, that is, down to the working pressure checked. 4, no leakage was found records should cook, in order to reduce the time to repair the atmospheric pressure. Pressure test meet the following cases, i.e., that qualified: 1, and no water mist on the walls of the pressure receiving element and weld metal; 2, after the pressure test, no residual deformation visible; 3, economizer tubes, and The interface is not leaking.

Gas heating condensing boiler is an international industry trend: a growing world energy shortages, rising energy prices, although domestic gas price is relatively cheap, but the price is only a matter of time; high-efficiency condensing boilers, low energy consumption, is energy-efficient the inevitable choice, is the future trend of development; when their investment and benefit ratio to a reasonable range, which is the period of great development; in Europe and other developed countries has reached this level. Condensing boiler environmental protection, low NOx emission, gas is the direction of product development.

Recently, Jilin Province Shuangliao municipal authorities about illegal sewage and coal-fired boilers, industrial furnaces remediation work held a mobilization meeting.

Stressed the meeting, do a good job on illegal sewage and coal-fired boilers, industrial furnaces rectification work is to implement the central, provincial party committee decisions need to be deployed, is the need to lay a tough fight to win control of pollution is an urgent need for the construction of ecological civilization shuangliao , is fully successful completion of all levels of environmental inspectors "looking back" need feedback rectification work. Must always adhere to the concept of green development, environmental protection as an intrinsic factor in economic development, internal driving force, implement the most strict system, the most stringent rule of law, provide a strong guarantee for ecological construction.

Meanwhile, the meeting also called for, to understand the situation, address the gap, and enhance the sense of urgency, a sense of responsibility, strengthening conscious selves, issue-oriented, problem remediation ton output capacity determination to do a good job, rectification, lay the winning pollution prevention tough fight; to strengthen measures to intensify its efforts to promote detailed work task decomposition, do a good job related information in archives, a good grasp of time node, to ensure the completion of various tasks by time nodes; to strengthen departmental interaction, resolutely carry ecology political responsibility for environmental protection, and make concerted efforts, up and down, "a game of chess," the formation of remediation work together effectively to the work realistically catch fine catch results.

At the meeting, he conveyed the "Opinions on rectification of illegal sewage behavior" and "coal-fired boilers and industrial furnaces comprehensive improvement plan", and the related issues note highlights.
