This formula is calculated according to the running costs of the case of complete combustion of the fuel gas boiler, practical applications to higher gas consumption, gas consumption in the calculation of the gas boiler should take full account of the calorific value of natural gas, boiler efficiency, so calculated the value to be able to meet the actual situation.

the cautious layout of the horizontal boiler chimney

The horizontal boiler, as a heat engine, has offered enough power for china’s industrial production. With the increasing application of the boiler, the problems raise. This passage will introduce the reasonable layout of the boiler’s chimney. After purchasing a boiler , the buyer need to install a chimney according to the boiler size and the site. The following are the relevant installation notions of the steel chimney and the brick chimney. notions for steel boiler chimney:

1.the steel chimney should be tough and hard enough. The chimney’s thickness should bear certain corrosion allowance. When the height of the chimney reaches 20~40cm,the diameter 0.2~1.0 m, the thickness of the body wall without liner should be 4~10mm, the body with liner should be 8~18mm.

2.The steel chimney’s lining can be born in subsection, the cracks between every two sections of 4~6m should be 20~50mm long. And the protection board should be installed on the top of the chimney. The chimney and the basic connection are made to conical support plate with the thickness of 20~40mm.

3.The steel chimney is better to choose the stainless steel one manufactured by the specialized factor. When the ratio of the chimney to the diameter exceed 20, a liable traction rope must be set, the rope should be 3~4 along the circle. Notions for the brick chimney :

1.the height of the brick chimney should not more than 50m. The chimney should be equipped with maintenance ladder and lightening rod. Meanwhile, the bottom of the chimney should be set with a 0.5~1.0m dust hole.

2.If there are two connections between the chimney and the horizontal flue, the two connections should be set in the opposite direction and be separated with a board . The part higher than the horizontal flue should not less than its half.

Boiler startup control method of a boiler drum water level during the startup process, drum level should be adjusted according to the change control kotelshchik conditions. (1) the initial firing, boiler water is gradually heated, vaporized, expanded, the water level rises, this time not by accident door drainage water level decreases, the door should be periodically sewage discharge, can improve the water quality of the pot, and promote circulation. (2) With the increase of steam pressure, steam temperature, the amount of exhaust is increased according to the trend should drum level, replenish the water supply. (3) After flushing pipe or boiler door safety check, often due to a sudden increase in the steam flow rate, steam pressure and serious downhill "false water level" phenomenon, thus performing the above operation should be preceded kept low level, then increase the water supply according to changes in the flow of steam, causing the water level is too low to prevent the safety valve seat and other reasons. (4) The load of the boiler case, the feed line switching operation in a timely manner, and in accordance with a predetermined condition, into the automatic water supply device is operated.

Cooperation with the fast boiler really is a very correct decision of our hospital. The party quickly boiler shell not only provides us with high-quality and high-performance energy saving boiler coexist; also provides free installation and post operation and maintenance personnel training services for our system, very caring, thoughtful. --customer feedback
