how much the steel hot water boiler
On the protection of Henan gas boiler - safety valve (B) 1. Henan gas boiler safety valve must have the following means: ⑴ spring safety valve must lift handle means and preventing movement of the adjustment screw is screwed lightly. ⑵ lever-type safety valve should prevent movement of the self-apparatus and the weight beyond the limitation of the lever guide frame. Means ⑶ weight plate from flying off the safety valve should prevent static weight. 2. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. Several valves as mounted on a short tube directly connected with the drum, the passage sectional area of the short tube is not less than 1.25 times the amount of all the area of the exhaust valve. 3. Valve should normally be installed exhaust pipe, exhaust pipe should be as straight outside, and there is sufficient cross-sectional area to ensure smooth exhaust. Exhaust valve to the bottom of the tube should be fitted with a safe place of drainage pipe. On the exhaust pipe and drainage pipe not allow the installation of the valve. 4. Henan gas boiler valve seat throat diameter of not less than 25mm. Bleed tube valve should be installed in the drain pipe does not allow the valve means. Discharge pipe should be through a safe place, and there is sufficient cross-sectional area and freezing measures to ensure the smooth flow of exhaust. 5. Henan and safety valve for the gas boiler maintenance after a new installation, should check the safety valve open start pressure, pressure from the seat and the back seat pressure. Safety valve reseating pressure is usually the beginning of the start pressure 4 to 7%, the maximum does not exceed 10%. When the pressure is less than the beginning of Kai 0.30MPa, back seat a maximum differential pressure of 0.03MPa. The course of the general safety valve should be checked every year. After checking the safety valve, which began Kai pressure, pressure from the seat, back seat pressure calibration results should be recorded in boiler technology files. After the safety valve by check, should be locked or seal, is strictly prohibited heavy object, move the hammer, the spool stuck any other means to increase the pressure relief valve or safety valve open start failure. Henan gas boiler in operation, the safety valve is strictly prohibited splitting. 6. To prevent adhesions safety valve plug and seat, should regularly do manual or automatic safety valve exhaust, turn on the water test.
And condensing boilers generally use clean energy such as natural gas as a fuel, has great environmental protection. In addition, the condensing boiler also has other advantages, with a look. A modular operation more simple design using a condensing boiler combined into a plurality of sections of the design pattern, the mounting structure is simple, the use of flexible and convenient. Simply refers to: split the original single large boiler dry N plurality of small boilers. This design allows the boiler by the number of "simple parallel combination" may reach the size of any single boiler, so many users choose this status condensing boiler to replace the various types of heating and how much the steel hot water boilers. Second, to reduce maintenance costs condensing boiler heating system boiler, including its internal control system and automatic gas control system, no working system can achieve a high degree of artificial effect, greatly reduces the labor costs. And condensing boiler through continuous optimization of design, process design condensing boiler, matching equipment level to a new level, to enable them to better serve the industrial production. Third, due to the smaller footprint smaller storage capacity of a condensing boiler, the temperature of heat up very quickly, only a few seconds, without generating excess heat loss. And because of its small storage capacity, so that the condensing boiler smarter structure, small volume, light weight, even if it is placed in the roof is also very convenient. And the use of condensing boilers can also save investment investment.
3, the structure of scientific and rational design
Condensing steam boiler has been able to have good thermal effects, lasting supply of energy, because the main reason is that scientific rationality in the structural design of the boiler. For example an energy saving and a condenser at the rear, not only can help improve the efficiency of condensation of the steam boiler, and excellent selection of panel material great protection and thermal insulation performance of the sealing steam boiler using condensing process.
The onset of winter, is located in Jilin Province Dongliao has entered the heating season. Recently, the Market Authority early planning, meticulous planning, to increase the safety supervision of the winter heating boiler, ensure the safe operation of heating boilers, curb the occurrence of all kinds of accidents, to protect people's safety, warm through the winter.
Market Authority set up a special investigation and remediation work organization boilers, special equipment to carry out self-examination from the security situation boiler heating units used to implement the main responsibility for the use of special equipment unit; simultaneous information collection boiler safety hazards, analyzing, improving risk control mechanism, proper risk monitoring, early warning and disposal of systematic risks and hazards should be reported promptly and truthfully; submit the initiative "special equipment unit security risk self-examination and self-change information tables to special equipment safety supervision organs ", and accept the supervision and inspection of the market, ensure that the boiler control risks effectively.
As of now, the council inspected the heating boiler unit 13, heating boilers and other special equipment to check 18 times, investigation and security risks 3 onwards, has been completely removed. The bureau said the next phase will further increase the safety and inspection of heating boilers, heating boiler unit supervise the implementation of the safety requirements, ensure that the heating boiler and other special equipment safe and stable operation. While strengthening the duty to timely and properly handle emergencies, a comprehensive good winter heating special equipment emergency security work.
