High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ and reduce heat lost.Sufficient steam storage room and heating area to generate high quality steam and high thermal power.Condenser is added to recycle the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce flue gas emission temperature and increase the thermal efficiency over 98% and save operating cost.

Environmental protection

Big combustion chamber equipped with Low emission combustion burner effectively reduce the NOx to 30mg/m3. Smoke duct and smoke outlet use internal insulation to reduce operating noise.

Combustion chamber uses full membrane water cooling wall structure and pressurized combustion without smoke mixture.

Energy conservation

Good quality alumina silicate fiber and fire clay insulation material are used and the boiler body temperature is controlled below 45℃ and greatly heat loss is reduced. Combustion chamber is designed with narrow distance tube membrane water cooling wall which has good air proof to reduce heat lost and increase boiler thermal efficiency. Internal inspection holes uses high-alumina refractory and manhole cover seal devices, solving superheat problem in this part caused by using refractory bricks.

CNC manufacturing technology

The key processing technologies such as steel plate blanking, circling, drum and tube plate drilling adopt advanced CNC machining to reduce the assembly stress and prolong the service life of the boiler.

Steel tube cutting, thread tube pressing and convection tube processing all adopt advanced CNC technology.

Automatic production line.

CROSBY STYLE JB PRESSURE RELIEF VALVE PRODUCT OVERVIEW Traditionally, overpressure protection for large piping and vessels in power and process plants has been satisfied by multiple T-orifice pressure relief valves. Style JB-TD are ‘above T’ orifice relief valves that represent a low cost alternative.

Boiler Pressure Relief Valve Temperature and Pressur

Temperature and pressure relief valves do precisely what their name states: They help provide automatic temperature and pressure protection for hot water heaters and supply tanks. Valves feature a test lever that can allow pressure checks during operation.

Sizing Pressure-Relief Devices - AIC

The set pressure of a relief device is the pressure at which the device operates. For spring-operated relief valves, small amounts of leakage start to occur at 92–95% of the set pressure. A relief device’s overpressure is the pressure increase over its set pressure, usually expressed as a percentage of the set pressure.

Pressure Relief Valve Inspection Frequency Table | Valv

ASME Code requirements The important sections of the ASME Code which deal with pressure relief valves are Section I {Power Boilers}. for better emission control performance (Fig 2). the specification of ASME Code symbol stamped pressure relief valves assures the end-user that the performance requirements defined in the Code has been verified.

Pressure Relief Valve Engineering Handbo

Reference is made to the ASME Boiler and Pressure Vessel Code, Section VIII, Pressure Vessels. The sole source of power for the pressure relief valve, therefore, is the process fluid. Most pressure relief valves, therefore, have a secondary control chamber or huddling chamber to enhance lift. A

Safety valve - Wikiped

A safety valve is a valve that acts as a fail-safe. An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits. Pilot-operated relief valves are a specialized
