water tube boiler for clothing industry
Economic interests condensing water tube boiler for clothing industry: condensing boiler can be recovered fuel type and boiler water temperature and how much water vapor latent heat boiler flue gases are using. When the ordinary recovery boiler combustion gas without condensation, the heat efficiency of the boiler if the calculated calorific value of the fuel was 90%, the use of condensing heat recovery unit, the exhaust gas temperature down to 30 ~ 50 ℃, the thermal efficiency will be increased to about 107%. In the case where the fuel consumption is constant, the lower the heating system return, the more condensing heat recovery heat recovery, the higher the thermal efficiency of the boiler. A boiler to provide heat for the winter the water conditioning water ring, which heating hot water temperature is 25 ℃, condensing boiler using a considerable saving than the conventional hot water boiler operating costs. 1 million kcal / h boiler, for example, natural gas consumption of the conventional type boiler 126.5Nm3 / h (natural gas low heat value 8500kcal / Nm3), consumption of natural gas condensing boiler 110Nm3 / h, when the boiler is operating 10 hours a day, heating period is 100 days, then, a condensing boiler using natural gas 16500Nm3 savings per year, using natural gas meter price 1.8 yuan, an annual operating cost savings 29,700 yuan.
In early November, Luyi County, Henan Province Quality Supervision Bureau organized a safety inspection activities on the water tube boiler for clothing industry in the area, ensure the safe use within the jurisdiction of the boiler in winter.
The main focus of inspection units use boilers to see through the following points:
First, the use of registration, maintenance, periodic testing situation.
Second, the establishment and implementation of the system and the rescue plan.
Third, if the boiler worker certificates.
Fourth, the operation of the boiler water treatment facilities.
To date, Luyi County Quality Supervision Bureau has complete supervision and inspection work on 11 units in the boiler, the inspection found problems and risks, monitor the instruction issued according to the law, clearly boiler rectification matter and time.
Note industrial water tube boiler for clothing industry water quality testing of water quality testing what are the considerations which industrial boilers (1) pay attention to scaling problems boiler. When carrying out inspections of the boiler water quality, pay attention to the problem of scale boilers. Boiler heating surface scaling, will not only affect the thermal conductivity of the boiler, but also can disrupt the normal structure of the boiler, affecting the normal operation of the boiler. Fouling will too concentrated so that the temperature of the steel sheet, the steel sheet could afford once over, will produce accidents. Moreover, the scale problem is a common cause of boiler accident, we need to attach great importance to staff fouling problems, do water quality testing. (2) pay attention to water treatment and work-related training of personnel. First, we must strengthen the progress of the work of the boiler water treatment, understand the importance of water treatment. Second, we must strengthen the training of staff so that it can fully understand the water treatment process. To make it have the necessary knowledge of water treatment. In particular, to strengthen the natural water, the impurities in the water for effective treatment to improve water quality. To pay attention when handling method, common in two ways, first, filtration, and second precipitation. In personnel training, to ensure that staff can master the common water quality testing methods and treatment, to master the professional knowledge, and constantly improve the quality of personnel. First, to ensure accurate test results of water quality, so as to smoothly guide the follow-up by the correct data. Second, we must strengthen the technical quality of the staff increase, so do the theory with practice. Third, the development of sound, a sound regulatory framework, the rule-based quality inspection can reduce boiler performance problems caused by poor water quality. (3) prevent boiler corrosion problems. Boiler corrosion problems need attention, which need to focus on sensitive monitoring of the boiler, the weak link in the water quality testing, monitoring whether it is corrosive. If the monitoring to corrosive media, to fully, completely clear. Taking into account the protection of the cold parts of the corrosion-prone parts of timely protection, corrosion has been the site for processing, so that you can effectively avoid the boiler cause further corrosion. (4) strengthen the supervision of water treatment. To further strengthen the supervision of the water treatment process, so as to improve the performance of the boiler, saving operating costs, reduce the occurrence of accidents. First of all, to supervise water quality around the normal operation of the boiler, to avoid adverse water quality. Second, we must strictly examine the quality of treated water in accordance with the relevant requirements, the supervision carried out, to achieve the quality supervision and inspection of the entire process. Only strengthen supervision, the implementation of routine inspections in order to truly improve the effectiveness of water quality tests.
Notes 1 water tube boiler for clothing industry installation, low temperature hot water floor radiant heating system has not been calibrated, non-operational use. 2, commissioning low temperature hot water floor radiant heating systems, it should be provided under conditions of normal heat and power. 3, the heating must first fill layer concrete curing period ends, and after the filling layer is completely dry. 4, debugging low temperature hot water floor radiant heating system should be carried out in the construction unit construction unit fit. 5, during the initial heating, hot water heating should be gentle, the water temperature should be controlled at higher than the ambient temperature was 10 ℃, and should not exceed 32 ℃. At this temperature, it should be run continuously 48h; 24h after every 3 ℃ elevated temperature, until the water temperature reaches the design. In respond to this temperature each fraction, a heating tube connected to the sump by way adjusted until normal operation. 6, the heating effect of low temperature hot water floor radiant heating systems, should be at the center of the room to 1.5m from the ground bulb thermometer indicating the temperature of the black, as the basis for the evaluation and assessment.
