three return pass gas fired hot water boiler

First, the design principle WNS type boiler and a gas main features. 1, WNS type boiler design principle and structure: WNS is a wet back boiler shell three-pass horizontal fire tube boiler, this structure uses three return, the oil mixed with air or gas well through the atomizing burner, in the complete combustion furnace in a corrugated, folded from the rear chamber into the first tobacco smoke return tube, to a second smoke box to the front return pipe tobacco, tobacco after entering the last tank, is discharged from the chimney. It has strong adaptability to different fuels, combustion of heavy oil, light oil, natural gas, city gas. Low power consumption, load regulation ratio. Boiler automatic control, adaptability of the burner. Using imported burner, reliable performance, high degree of automation. 2, the main features of the WNS type boiler: High (1) combustion efficiency, safe and stable, space-saving, fuel-saving, low investment costs to buy fuel; (2) full-pull edge butt welds, boiler safety, long life, maintenance costs low. (3) there is arranged a tail flue gas condensation recovery, can effectively control the exhaust gas temperature, high thermal efficiency of the boiler; (4) with automatic burner, water continuous electric adjustment, high combustion efficiency. (5) The quick configuration, the entire boiler design on the steel strong base, easy installation and transportation, saving the boiler room floor space area. Two, SZS type gas boiler structure and characteristics: SZS longitudinal type double drum "D" type arrangement quick water boiler. It consists of upper and lower drum, membrane wall, the convection tubes, condensers, and economizer, disposed in the front wall of the burner, the combustion of the fuel in the furnace, flue gas convection bank, an economizer and a condenser into the chimney. The main features are: (1) The double boiler drum "D" type arrangement, compact, small footprint, good flame fullness. (2) the boiler supporting mode can be free to expand upwards. (3) furnace wall and membrane in all convection pass wall structure, good sealing and maintenance work and reduce the use of refractory bricks. (4) The quick boiler structure can effectively shorten the installation cycle. (5) arranged economizer tail, can effectively reduce the exhaust gas temperature, high thermal efficiency of the boiler. (6) The whole boiler steel seat strong base, easy transportation and installation. (7) having a heating surface surplus, soda and a sufficiently large space to ensure stable boiler parameters. (8) with automatic burner, combustion efficiency and an ignition control program and overpressure, flame protection. Third, the application type WNS and SZS boiler used in Example 15 t: In addition to evaporation, working pressure, as the fuel is used, the two contrast, WNS size slightly smaller type gas boiler, small footprint, from a cost perspective, slightly lower than SZS type gas boiler, the thermal efficiency of the boiler is almost the same, but their difference only lies between 1 t -20 t tonnage, the conventional WNS type gas boiler, and SZS-type gas-fired boiler more than 4 tons -60 tons, even to 90 tons.

How to judge whether the burning oil and gas boiler is extinguished or not?

The indication value of the negative pressure gauge of the fuel gas boiler furnace suddenly increases; the inside of the furnace becomes black, the flame is not seen by the fire hole; the burning sound of the furnace disappears; the fire monitor emits a fire extinguishing signal; the temperature and air pressure drop sharply, and the water level drops first and then rises. These are all flameouts. If the auxiliary fan accident causes a flameout, if the power supply of the induced draft fan or blower is interrupted, there will be an accident signal; if the fuel supply is interrupted, the boiler fuel or gas pressure will drop to zero.

10 tph WNS series gas-fired fire tube boiler for hospitals

The Second Hospital of Jilin University is a third-class & first-grade comprehensive clinical hospital. Hot water and steam are essential energy sources for large comprehensive hospitals, providing adequate steam heat energy support for hospital heating and daily disinfection. Under the background of current energy-saving emission reduction and refined management, the Second Hospital of Jilin University actively responded to the national "coal to gas" policy and decided to replace the old boiler equipment with low efficiency and high emission.

The safety inspection operations will be based on "regarding the development of boilers and industrial emergency notification equipment and facilities safety inspection of" (Wei Safety Office Zi [2019] No. 23) documentation requirements, earnestly implement the regulatory responsibility, and actively carry out arrangements, combined with Cravens practical, clear pressure boiler safety inspection work content and division of tasks.

In conjunction with the National Health City welcome the review investigation work, based on their job functions, all members of the team to take the sinking line, full package by, Division linkage approach, focusing on whether the boiler to handle the use of registration, whether periodic inspection, workers who whether induction certificate, the safety valves and pressure gauges and other safety accessories boilers are using the site regularly check verification, the highest level gauge whether there has been a minimum level of safety markings for verification. 54 boiler region's 24 units were one by one investigation. Up to now, all 33 units in the boiler are in an examination period, in line with the requirements. It has two boilers to handle the deregistration, and 19 boilers have long-term disabled, is now urging the use of units to seize deregistered.

While actively step up publicity and training efforts, and send more professionals to communities, cooperatives were the main person in charge of safety knowledge of professional training, to explain the basics of boiler and check focus, effective universal safety knowledge, improve regulatory efficiency.
