What is exact Boiler heating surface

Boiler heating surface refers the interface that absorb heat from the heat medium and transfer to the media, includes convection heating surface and radiation heating surface. radiation heating surface is the interface mainly absorb heat radiation from the heat release medium, Such as water wall tube and the furnace. convection heating surface is the interface that in Convection exchange heat way absorb heat from the high temperature flue gas, usually refers to the heating surface that flue gas through,such as flue, convection tube.

How Sitong Coal Fired CFB Boiler Anti-Wear

New technology is used in circulating fluidized bed boilers manufactured by Sitong to realize anti-wear. High temperature separator is set in front of the superheater and economizer to largely reduce the inlet flue gas density and refine the particle size. All the separator inlet, separator wall, separator outlet, and return feed device use corundum wear castable or plastic material. Due to high quality materials and reasonable design, the coal fired CFB boiler manufactured by Sitong Boiler is anti-wear and have long service life.

Shutting down your boilers for the season

Improper storage of your boiler can lead to a series of problems from general tube thinning due to oxygen attack to complete tube failure, including burner controls and valves. According to the statistics, burner failures is responsible for 85% fatal power boiler incidents. If your steam boiler operates at over 15psig it is a power boiler. Never store a dirty boiler.

How many boilers are needed

Some applications require one boiler at all times, while others may require multiple boilers during peak times and only one boiler most other times. Some facilities actually require multiple boilers at all times for redundancy. Whatever the case may be, consideration should be given to back-up equipment in preparation for future expansion, unexpected delays, and routine maintenance to keep the boiler running efficiently for years to come.

AUXILIARY EQUIPMENT

Effective and efficient boiler operation requires the use of auxiliary steam plant equipment. For some projects, users can pipe their existing auxiliary steam plant equipment to the new or rental boiler for safe operation. In other cases, new or rental auxiliary steam plant equipment may be required. Water Softeners To optimize boiler performance and avoid costly maintenance, the impurities of water must be removed before the water enters a boiler system. Hard water, or mineral rich water, can clog the tubes and water side of the boiler leaving calcium scale deposits which act as an insulato

Steam boiler and hot water boiler

The primary purpose of a boiler is to supply energy to a facility’s operations, and the nature of the application will dictate whether you will need a steam or hot water boiler. Hot water, or hydronic heating boilers are commonly used in heating applications. The water supplied by the boiler is usually 180F to 200F, but if system requirements call for temperatures greater than 240F, a high temperature hot water boiler can be supplied. Operating pressures for hot water boilers are generally 30 to 125 psig.

SATURATED VS SUPERHEAT

In a boiler, energy from the fuel is transferred to liquid water in order to create steam. Once the water is heated to boiling point, it is vaporized and turned into saturated steam. When saturated steam is heated above boiling point, dry steam is created and all traces of moisture are erased. This is called superheated steam.

WATERTUBE VS FIRETUBE

Two main boiler types are Watertube and Firetube Boilers.Deciding which type to choose for your application is not easy. Watertube and firetube boilers are opposite in design. In a watertube boiler, water travels through tubes which are surrounded by the by-products of combustion, or flue gas. In a firetube boiler, the flue gas travels through the tubes, which are surrounded by hot water. Firetube boilers are typically designed with either three or four sets of tubes (three- or four-pass boilers). Every set of tubes that the flue gas travels through is considered a “pass”.

How to Safely Operate Gas Boiler?

Boilers are widely used in living and industry. In recent years, gas boiler replaces the old type boiler with high pollution by hotel, bathing, restaurant, food processing, institution, schools, hospitals and other enterprises to improve the air quality and the living environment. Boiler is pressure vessel. Natural gas as fuel of boiler is combustible. So six points are required to ensure safe operation of the gas boiler. Blast doors must be set on the boiler and flue (Sitong boiler using our own patented technology - self-sealing blast-resistant door).

What are the Features of CFB Hot Water Boiler and Steam Boiler

the features of circulating fluidized bed hot water boiler and steam boiler 1.Convenient operation. For hot water boilers, it is water that flows in and out. Except the steam and water both used boiler, you only need to monitor the boiler’s pressure and the temperature of outlet water and return water. Don't need to monitor the liquid level. 2. When the hot water boiler power off or pump power off , the pot water is easy get vaporize. Measures must be taken to ensure the boiler runs safe and reliable.
