chain grate industrial boiler in hotel

Oil-fired chain grate industrial boiler in hotel to start the program in the previous article we introduced a program to control the relevant requirements of the first auto-ignition process of oil-fired boilers, meet us on the basis of a second to explain it part of the program control. Program control is divided into start, normal operation, normal stop three parts namely: (1) before starting the purging fire a little bit sparking a fire flame monitoring. Work (2) oil-fired boiler (3) a flame monitoring a low load pressure, temperature monitoring a large, converted a small fire start and stop automatically convert a load adjustment. (3) Normal After purging a fuel cut stopping the program returns to a zero position. These are dynamic program of three major oil-fired boiler, hope can help you. Oil-fired boiler cleaning solution before the oil-fired boiler cleaning boiler must be based on the actual situation, formulated cleaning solution from the professional and technical personnel, and approved by the technical director. Cleaning solution should include the following: (1) Name of boiler, boiler model, registration number, age and put into operation last pickling time; (2) the presence of defects boiler; (3) boiler fouling or corrosion conditions , including scale distribution, thickness (or the amount of sediment), and equipment status scale analysis; (4) washing the scope, the cleaning process; (5), the cleaning process and small scale test material ,, the amount of oil-fired boilers and boiler structure concentration, determined cleaning system cleaning agents, corrosion inhibitors, and other additives of passivating agent, dosage and washing temperature, time and other conditions; (6) chemical cleaning system of Fig; (7) need to be taken boiler cleaning section flow, isolation, protection; (8) the process of cleaning the boiler, monitored and recorded should project; (9) the cleaning process waste liquid discharged; (10) after the washing or cleaning residual dirt cleaning, quality inspection washing conditions. Boiler chemical cleaning should be strictly enforced wash program, if there are special circumstances need to change the program, should sign an agreement approved by the technical director of the original program. To ensure the safety of oil-fired boiler equipment, in strict accordance with relevant cleaning system to carry out.

Gas hot water chain grate industrial boiler in hotel in the use of the process What are the requirements for water and water temperature? Gas hot water boiler in the use of the process has on water and water temperature What are the requirements? In general, gas hot water boiler water temperature is no uniform requirement, the need for specific requirements based on furnace and boiler equipment such as its model, the basic points for the high and low temperatures two kinds. In addition, for each boiler water temperature control, are provided with an alarm device, once the phenomenon of over-temperature, alarms will alert to remind fireman timely adjustments. Of course, for boiler water quality this one, if the water is not up to it, then the impurities in the water will cause the boiler appears scaling, corrosion and other phenomena during the latter part of the operation, thus affecting the safe operation of boilers and other operating life and quality of supply etc., must be strict control of boiler water quality, treatment compliance. In short, both the gas hot water boiler water quality or temperature of the control must do rigorous, at their job, do their business, should not sloppy, resulting in unnecessary human and material losses.

Check items Notes steam chain grate industrial boiler in hotel and a steam boiler inspection Annex 1, the steam boiler pressure gauges, they check whether the abnormal water table, bend, and the intermediate connecting pipe mounting valve opening and closing without exception. The table below shows the water level is correct, whether the water table column drain valve correctly state, pressure gauge whether there is a statutory inspection mark within the time limit. 2, steam boiler safety valve, drain valve, vent pipe to check whether they have been adjusted to a predetermined opening pressure, vent pipe installation is reasonable. Check the vent pipe is blocked, whether the anti-Chen measures. 3, the opening and closing of the drain valve discharge inspection device is flexible, the gland liner whether to allow sufficient room for adjustment. Outfall road if there is an abnormality. 4, the main valve, the water supply shut-off valve and non-return check tie their open and closed states without exception, if the valve cover material left margin. 5, the air valve in the hydrostatic test water to full state, the start point of the furnace to appear vapor must be kept open state. 6, connection pipe inspection gas and water pipes, the support, the telescopic joint, and whether the hydrophobic insulation and meet the requirements. After scaling will overheat the metal, the metal will stretch creep, modifications, bulge, serious overheating of the tube when the storm. Scale layer is a heat medium and the metal wall; between the water vapor, since the scale layer is small thermal conductivity, a significant insulating effect, greatly increasing the temperature of the metal wall fouling. It is estimated that the evaporation heating surface, furnace deposited scale often overheated collapse, deposition of scale by the pot shell (drum) regular hot drum kit, the heating surface tubes deposition of scale is often overheat storm tube larger fuel amount of waste. Daily work to do steam boiler inspection matters, in order to ensure normal production.

In recent years, Siyang County town chrysanthemum industry as part of the ecological projects to enrich the people in the choice of chrysanthemum drying equipment, the county Environmental Protection Agency proposed to replace coal-fired chain grate industrial boiler in hotels to electric boilers idea. Part chrysanthemum growers is objected that the idea costly and cumbersome, but after analysis and explanation of the Environmental Protection Agency and the power company personnel, electrical boilers have a deeper understanding of the use of electric boiler can not only improve drying chrysanthemum chrysanthemum quality and product phase, it did clean, safe, and there are various government subsidies, while coal boiler if the government out of the use, post-investment costs will be higher. At present, the boiler "electricity for coal" action has been noticed.

In recent years, Siyang County uphold the "gold and silver mines that lies to" development concept, vigorously implement alternative energy projects, alternative energy gradually extended to grain drying, drying fruits and vegetables, herbal drying and bathroom, hotels, restaurants, businesses and other industries. Siyang county party secretary said: "Winning 'Battle of Blue Sky', shouting slogans alone are not shouting to the sky, or from the 'coal to electricity,' 'oil to electricity' these specific things to start, through the implementation of alternative energy engineering, elimination of high energy consumption, low-energy-efficient equipment, the progressive realization of ecological priority, green development goals. "

Since 2016, the county completed a total alternative energy companies, service unit 686, phase out coal boiler 1336 units, to complete alternative energy electricity 256.69 million kwh. Energy saving alternative to business spending, reduce production costs and improve their efficiency and realize a production of "zero emissions" to protect the party clear water and blue sky. In mid-November, Siyang County was selected as "the second batch of national ecological demonstration counties civilization."
