water limits as per in high pressure boiler

The gas-fired water limits as per in high pressure boiler will have a series of chemical and physical reactions in the furnace during its operation. In the process of use, it will effectively form its hard and dense scale on the heating surface. This will directly lead to the reduction of heat transfer efficiency and corrosion factors under scale, which will lead to the reduction of boiler water wall furnace heat absorption.

Depending on the application, energy-saving gas-fired mainly divided into the following two categories.

First, heating boilers, boiler bath

matters needing attention in selecting the Brand of Gas-fired Boiler

With the increasingly serious air pollution and the expansion of the weather and scope of haze, the state has implemented a series of measures to convert coal-fired boilers into gas-fired boilers, and gas-fired boilers have become the first choice for heating production in enterprises. Domestic market sales of gas-fired boilers are very many types of gas-fired boilers in the selection and purchase should pay attention to distinguish.

Special equipment to do the field work safety supervision, to further improve the water limits as per in high pressure boiler enterprise security management, implementation of corporate safety responsibility; March 13, Gaomi City, Shandong Province Security Committee held a boiler corporate safety training sessions. The meeting was attended Market Authority official in charge of the business section chief; towns full-time deputy director of the Office of District Administration of Work Safety; 402 boiler business person in charge, the Boilermakers; 157 appliances can replace the user responsible for the project.

The meeting of business leaders and boiler related use Boilermakers were safe to use boilers special training. At the meeting, Municipal Emergency Bureau is mainly responsible for a speech, requires the use of boilers enterprises to strengthen security awareness of employees, improve the professional level of employees, establish and improve mechanisms to ensure the safe operation of the boiler.
