The problem of Feed-water for Boiler in Thermal Power Plant

Large and medium-sized boilers in the power and heat industries have high economic losses due to high operating parameters, and the original boilers are smashed. The social impact is huge. Therefore, the water quality of boiler feed water is particularly high (water quality required for power plant boilers, resistivity) >5 MΩ.CM, SiO2 <20 μg/L). In general power plants and thermal centers, water plants are set up to treat boiler feed water.

In late May 2018, Hedong District, Tianjin Environmental Protection Bureau, the District Construction Committee, District Bureau for approval jointly held low nitrogen gas top class dhl boiler reconstruction work will push for the Municipal Environmental Protection Bureau atmosphere at the meeting of May 18 Air pollution control work in progress briefing involves the transformation of low nitrogen gas boiler, convey the contents of the meeting and introduced the progress of work and experience low nitrogen gas boiler reconstruction of other counties.

Clear four key tasks meeting: First, all gas boiler units must be in accordance with the time node, complete technical solutions before the end of May to develop and expert appraisal work;

Second, according to the requirements of the minutes of the 49th executive meeting of the district government, the units shall, not later project work next week to start the project, and accelerating project bidding, project construction to ensure completion before the end of September;

Third, the units should seriously accordance with the "Municipal Environmental Protection Bureau of Finance on the issuance of Tianjin Gas boiler low nitrogen fixed subsidy reconstruction project implementation approach" (environmentally friendly gas-chun [2017] No. 171), "on the issuance of Tianjin Municipal Environmental Protection Bureau letter fixed subsidy acceptance requirements of low nitrogen gas boiler reconstruction project "(Tianjin environmental Protection memo No. [2017] 406) and" Municipal environmental Protection Bureau Municipal market supervision Commission letter of relevant work requirements transformation of low nitrogen gas boiler "(Jin Han [green gas the relevant procedures 2018] No. 92) requirements, preparing project application and acceptance, with particular attention to security issues in the process of transformation of the project, to ensure that emissions meet the standard requirements after the transformation;

Natural gas top class dhl boiler risers arranged in the corner of the room as much as possible the natural gas boiler standpipe arranged in the corner of the room, especially at the junction of two exterior walls. On each riser pipe, the lower end of the valve should be installed, turn on the water for inspection. For small riser systems can also be supplied only in the partial rings, valves coat return water pipe. Double-pipe water supply system is typically placed on the right side facing the riser when the riser and manifold intersects competent should bypass manifold. In addition to the stairwell and the auxiliary room (e.g., toilet, kitchen, etc.) can be combined with a standpipe, the standpipe is generally advised separately provided, so as not to affect the heating space at the time of inspection. Return water pipe can be laid on the ground, does not allow the laying of time (e.g., when married), or not enough headroom, return water pipe passage disposed in a semi-trench or trench on the floor to pass. There are two approaches, should be located at a distance from movable cover, married trench should be provided movable cover, in order to repair the pipe trench every backwater interlude. Return water pipes should also be noted that there is a certain slope to facilitate draining. In order to exclude the air in the system, gas-fired, current tank should be provided at the end of the water mains, and the tank should be set in a room or place provided with a drainage facility. If you can not meet this requirement, it should be put to a place near the trachea drainage facilities in order to exhaust. In order to effectively exclude air from the system, all levels of water in the pipe should have a slope of not less than 0.002, usually 0.003 (mechanical or gravity circulation aspect according to the given cycle, as described above). As a result of conditions, mechanical circulatory system of hot water pipes can be laid without slope, but the tube is not less than 0.25m per second water flow.
