Gas pressure hot water boiler pressure introduction gas hot water boiler: gas pressure hot water boiler pressure vessel belongs, as always pressure hot water boiler is full of water, so no water level, but to be fitted with pressure gauges, safety valves and thermometers. Circulating pump pressure hot water boiler heating system is generally used in water pump, which is pumping systems engineering backwater sent to the boiler, it is necessary to overcome the resistance of the systemic circulation, but also to maintain a certain pressure boilers, hot water does not guarantee high temperature vaporization . Pressure hot water boiler can not only supply low-temperature water, but also to supply hot water Features: 1, boiler design, manufacturing, supervision and inspection are strictly according to "hot water boiler Safety Supervision" ensure long-term security and stability of the boilers. 2, the boiler body is a shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in combustion chamber a slight positive pressure, combustion heat load is low, less NOx emissions of harmful substances. Through advanced machine test bed to test several times to verify the boiler under various load operation can get good thermal performance, qualified flue gas emissions targets as well as a wide range of burner adapter. 3, before and after the boiler smoke box with a special heat insulation materials, high temperature, low thermal conductivity, good anti-radical quenching heat capacity, greatly extending the life of the smoke box. A lower smoke box is provided with a condensate drain, water condensed reduce corrosion of the pressure receiving member. 4, the boiler and each pot spout means disposed reasonable to optimize the pot water circulation, prevent scale generation, but also help to improve the water side heat transfer. Set hand hole, inspection hole in the poor circulation of weak links, to facilitate regular inspection and maintenance. 5, the temperature of the boiler smoke box structure compared to dry wet back boiler back, greatly reduced, the smoke box solves the frequent need to maintain the operation of the phenomenon; 6, a large volume of water boiler design, the load fluctuation of furnace not sensitive to large changes in the load range of users still apply. 7, industrial boilers professional artists and designers carefully designed appearance, novel and unique and yet with the surrounding environment coordination. Sino-Swiss boiler completely changed the image of heavy industrial boilers, industrial boilers is a new concept of low-carbon twenty-first century. Construction and installation points: 1 explosion-proof door is provided on the fuel, the rear of the gas-fired boiler or pipe smoke, explosion door location should be conducive to explosion venting. For gas explosion likely to endanger the safety of the operator occasions, should be installed on the guide tube pressure relief blast doors. 2. Installation of boiler and its auxiliary equipment, water treatment equipment should meet the technical requirements of the device manufacturer. Equipment foundation must be the arrival of equipment and after verification and design drawings before construction. 3. When mounting the device, the device should be avoided, to install the floor material are collected together. Column using a construction, the beam lifting device, must first verify that the carrying capacity of the beam, the column. 4. After the pressure test acceptance oil, gas, water, steam pipe installation, according to "Industrial metallic pipeline construction and acceptance" in GB50235-1997. The main construction practices and node configuration detail see National Building Standard Design Atlas. 02R110 "Gas (oil) boiler room engineering design and construction Atlas" 02R111 "small vertical, horizontal tank Atlas" 02R112 "Tank dome Atlas"

58MW SZS series gas-fired hot water boiler project for heating industryPeople cannot live a comfortable life without heating boilers in the winter, the normal and stable heat source is of great importance to human life. What is following is the increasingly serious problem of environmental pollution, implementing the policy of “coal to gas” is no time to delay, using gas-fired hot water boilers has been the general trend. Tianjin Jizhuangzi heat supply center is an enterprise specializing in city heat supply. In order to realize the “green heating”, the heat supply center decided to introduce a branch of gas-fired boilers to replace the old coal-fired boilers. ZOZEN successfully won the trust of Jizhuangzi heat supply center with its own strong comprehensive strength and rich experience in the heating industry. JIzhuangzi chose to cooperated with ZOZEN and ordered 3 sets of 58MW gas-fired hot water boilers (SZS58-1.6/130/70-Q) to provide heating source for citizens. This series of boilers adopts the design of " D " type membrane wall structure, the steam drum, the water drum and convection tube bundle form the convection heating surface to ensure the the boiler expands on both ends as a whole; at the same time, the combustion chamber is designed with the narrow distance tube membrane water cooling wall to reduce heat lost, in addition, the boiler is equipped with a big combustion chamber for the full combustion of fuel, effectively increasing the boiler thermal efficiency over 98% and reducing the NOx to 30mg, which are superior to the national level one energy efficiency standard.

To better implement the "Blue Sky Hongshan win the Battle of three-year action plan to implement the program," the job requirements, Hongshan Environmental Protection Agency to ban high-pollution fuel combustion zone 10 steam tons / hour coal-fired boilers to carry out a special regulation, and issued the relevant units of the "notice on deadline out of 10 steam tons / hour of coal-fired boilers."

May 5, the District Environmental Protection Bureau, Jia Guangsheng nuclear industry two hundred forty-three Brigade, WONG-school and other relevant units after receiving the notice from coal-fired boilers out of progress were examined, the examination requires companies to accelerate the implementation of the main responsibility, solid promote renovation work, to ensure the completion of coal-fired boilers out of the task on time.

Electric utility interest in supercritical pressure steam cycles has revived in the United States after waning in the 1980s. Since supercritical cycles yield higher plant efficiencies than subcritical plants along with a proportional reduction in traditional stack gas pollutants and CO{sub 2} release rates, the interest is to pursue even more advanced steam conditions. The advantages of supercritical (SC) and ultra supercritical (USC) pressure steam conditions have been demonstrated in the high gas temperature, high heat flux environment of large pulverized coal-fired (PC)boilers.
