fired solar water boiler

BFG fired boiler manufacturer

Blast Furnace Gas (BFG) fired boiler provide by zg horizontal boiler manufacturer which are used in various heat transferring applications. These BFG boilers conforms to the latest IBR & International code and are acclaimed for adequate heating surface, steam space, steady supply of steam.

What precautions (1) Note that before the boiler cleaning before pickling to confirm the nature of the scale, thickness and range; (2) pickling work must be carried out under the guidance of experienced technical staff, and the pickling solution through repeated appraisals, and develop practical pickling solution. (3) Regardless of the use of corrosion inhibitors are inevitably produce some corrosion on the boiler, the pickling is not a panacea, not multiple uses. (4) pressure drum member if cracks or other leakage defects, these defects must be clear prior to pickling, or pickling descaling allowed. (5) pickling, the operator should wear protective equipment, (anti-acid gloves, plastic aprons, masks, glasses, etc.), open doors and windows to enhance ventilation to avoid bodily harm. Prohibited welding, smoking or open flames access in the workplace to prevent hydrogen explosion causing personal injury and other losses. Smooth discharge of gases produced (6) should be pickling boiler feed water pump, and a steam outlet pipe sewage reliably isolated with a blind plate, opens drain valve, pickling. (7) Pickling temperature should be controlled at 5 degrees is appropriate. (8) pickling process findings and laboratory data must be carefully recorded. No operator of pickling technical experience, we must make the necessary technical training in advance, after passing the examination, to conduct independent operations.

At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the steam boiler used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.

Environmental issues boiler assembly Note: introduce a predetermined environmental protection boiler drum of the drum to be assembled longitudinal weld, the weld ring is assembled to the assembly welds and weld splicing head or both elements should satisfy the following requirements: the longitudinal seam or seal the actual welding seam edge deviation head sides of the steel sheet is not greater than 10% of the nominal thickness, and not more than 3mm; when the thickness is greater than 100mm, of not more than 6mm. Deviation of the actual edge seam on both sides of the steel sheet ring is not greater than 15% of the nominal thickness plus 1mm, and no greater than 6mm; when the thickness is larger than 100mm, no more than 10mm. Two abutting element or plate have different thicknesses and the edge of the book cut, treated according to the same plate thickness, the above-described nominal sheet thickness means; butt plate of different thicknesses, but with no thinning, the nominal thickness of the aforementioned finger planks . Any difference between the maximum inner diameter of the same cross-section and the minimum inner diameter of the drum should be not more than 1% of the nominal inner diameter. Angularity drum longitudinal seam should be no greater than 4mm. If the pressure detecting element via a weld joint defects found unacceptable, welding unit shall find out the reason, the development of a viable repair program to rework. Before welding defects should be completely removed. After welding, welding zone should be done appearance inspection and nondestructive testing. Heat treatment after welding element requirements, should be done after the welding heat treatment after welding. Rework the same position should not exceed three times. Repair parts, frequency and circumstances shall be deposited in the boiler repair product technical file. In the economic and environmental positive impact gas steam boiler
