takuma boiler

Why do many service sites choose condensing takuma boilers?

Condensing boiler is the so-called new generation boiler, it is necessary to use this kind of condensing boiler in heating or hot water supply, and the working efficiency of standard condensing boiler is very high. To meet the requirements of the efficiency of each site, the condensing boiler emerges as the times require, then why do many service sites choose the good after-sale condensing boiler?

1, designers of highly condensing boilers with strong operating performance will use modern software to assist in their work according to the requirements of use, and at the same time should conduct practical operation simulations in accordance with advanced design systems. Therefore, many operators say that it is easy to operate in the late stage of condensing boiler because the product design makes it have good operation performance, and the automation degree of condensing boiler is relatively high, which can almost realize unmanned operation.

2, strong durability, in view of the special working environment and operational requirements of professional condensing boilers, it is necessary to carry out a second durability analysis in production design, including material selection of condensing boilers and their later process technology and construction planning. Cutting and welding work is also responsible for cutting and welding. After completion of production, the condensing boiler needs to be polished and sprayed, so that its service life can be greatly improved.

3, the working environment of the weather-resistant / environment-resistant condensing boilers is generally worse. In some condensing boilers, there are not only a lot of wet gas but also many chemical corrosion substances, and the daily working frequency of the condensing boilers is higher. Therefore, it puts forward a new and higher requirement for its weatherability and environmental resistance. The condensing boiler can avoid corrosion through professional design. Therefore, the professional condensing boiler effectively evades the late fault in the later stage, which makes the service life of the condensing boiler longer and the failure rate lower.

Requests for gas steam takuma boiler valves 1, valves and flue gas system boiler tube baffle should be clearly marked, indicating valves and dampers name, number, and media flow direction switching direction, should the main regulator valve for opening degree indication. Valve, the shutter operating mechanism should be installed at a location convenient to operate. 2, the main steam valve should be installed near the outlet of the drum (potshell) or the header of the superheater. Boiler unit consisting of machine, the main steam valve the inlet of the turbine can be installed. Main steam valve vertical shell boiler may be installed in the boiler room to facilitate local operations. On each boiler steam pipe with steam header pipe is connected, cutting two valves shall be installed, it should be equipped with a drain pipe and cutting the valve between the valve open to the atmosphere, an inside diameter not less than 18mm. 3, equal to or greater than the rated evaporation 220t / h boiler to be provided to the remote air exhaust valve. 4, should be installed on the water supply pipe not Fractional economizer inlet feed water feed water shut-off valve and a check valve. For unitary unit, not fitted with a check valve to a water tube boiler feed water. The inlet of the economizer and separable leading drum (potshell) are mounted to the water supply pipe should be cut off the water supply valve and check valve. 5, the water supply shut-off valve should be mounted between the drum (boiler shell) (or economizer inlet header) and a water supply valve, and a check valve immediately connected with the water supply. 6, in the rated evaporation 4t h boiler / water regulator shall be installed automatically, and manual means mounted at a location feedwater control fireman who easy to operate. 7, rated boiler steam pressure greater than or equal to 3.8MPa of water should be urgently put in a minimum security indirect drum water level and normal water level, discharge pipes should be installed on the valve, once full of water occurs in order to promptly turn on the water. This valve must be turned off in the boiler running. 8, the drum (potshell), superheater, where possible accumulation of air reheater and economizer, etc. should be fitted with an exhaust valve. 9, different operating pressures to be independent of the boiler steam pipes and water pipes, respectively. When employed as a main steam pipe, the steam pipe must have a higher pressure automatic decompression device, and a safety device that prevents the low-pressure side of the overpressure (check valve). When the water pressure which does not exceed the maximum working pressure of 20% of the total water supply can feed water to the boiler system. 10, boiler feed water system shall ensure safe and reliable water supply. Boiler room should have an alternate water supply equipment. And the number of spare capacity and a water supply device is arranged water supply system, is determined by the design of the boiler room units according to the design specifications. 11, rated greater than or equal evaporated 1t / h boiler water sampling device should pot, when steam quality requirements, there should be vapor sampling means. Sampling means and the sampling point location should be taken to ensure that water vapor representative sample.

Recently, the Longhai carried out safety campaigns to the takuma boiler, the campaigns start from the four directions, whether units in accordance with the boiler 'boiler safety practices "to use the correct boiler conducted a comprehensive inspection.

First, the unit register in a boiler boiler inspection. The use of units to crack down on unauthorized use of untested or failed the inspection of boilers.

Second, the units are equipped with a boiler if the security officer and fireman personnel. Focus on checking whether the use of units as required "special equipment operator assessment rules," the fireman with security personnel and staff to meet the requirements, and whether the person has made fireman fireman card.

Third, in the boiler unit will be the safety management system, emergency plans to check the system; and to convey the importance of this inspection in the boiler unit, raise awareness of security units.

Fourth, strengthen supervision of energy-efficient boilers, boiler and actively promote energy efficiency testing, at present, boiler energy efficiency testing has been completed a total of 112 units.

To date, the Longhai inspection operations were dispatched inspectors 209 passengers, checked boiler unit 136, check the boiler 168 units, eliminate safety hazards at 9, and urge the use of sealed units to enhance the energy efficiency of boilers 21 units.

And with the Commission by letter, and environmental protection departments to further promote the comprehensive upgrade of coal-fired boiler energy saving project, disable the coal-fired boiler 53 units, 34 units scrapped, replaced by raw material boiler fuel and natural gas fuel of a total of 40 units, is out of the city coal-fired boilers to make a positive response.

Four ways to reduce the temperature of the exhaust gas takuma boiler: a boiler based on years of research experience, we found that the level of boiler flue gas temperature is directly linked to thermal efficiency. Exhaust gas temperature is increased by 10 ℃, the thermal efficiency of the boiler 1% loss, indirectly increasing the fuel input costs.
