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.

The oil and gas fire tube boiler produced by ZG boiler has been used in food factories for many reasons due to its simple structure, convenient operation, high cost performance and cleanliness. The natural gas, oil or other fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes. The fire tubes are immersed in water inside the main vessel of the boiler As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them. As a result, steam is generated in the water and naturally comes up and is stored in the water in the same vessel of Fire tube boiler. This steam is then taken out from the steam outlet for food processing. The water is fed into the boiler through the feed water inlet.

Technical features of WNS boiler

The WNS boiler produced by ZG boiler is a oil and gas boiler, which can be divided into WNS oil and gas hot water boilers and WNS oil and gas steam boilers, and is also a well-developed hot boiler by ZG boiler. The technical features of this boiler are as follows:

1. The WNS oil and gas boiler adopts a large-volume combustion chamber design, so that the fuel is fully burned and the flame fullness is good. Good for low-nitrogen combustion of fuels and low nitrogen emissions from flue gas.

2. The WNS oil and gas boiler uses an automatic low nitrogen burner + flue gas recirculation system (FGR) system to achieve ultra-low nitrogen emissions.

3. The WNS oil and gas boiler adopt advanced wave furnace structure, which not only increases the heat transfer area, but also satisfies the free expansion of the furnace after heating. At the same time, the waveform furnace structure enhances the disturbance of the flue gas and enhances heat transfer and combustion.

4. The rear of the boiler body is equipped with an energy saver and a condenser, which can effectively reduce the temperature of the exhaust gas and improve the overall thermal efficiency of the boiler. The condenser adopts "low temperature corrosion resistant" special steel to greatly increase the service life.

5. The oil and gas boiler adopts a wet-back structure and full-flanged butt welds with high reliability and low maintenance costs.

6. The use of threaded tobacco pipes in the WNS oil and gas boiler is beneficial to enhance airflow disturbance and enhance heat transfer.

7. The WNS oil and gas boiler outer packaging adopts color pattern board, mirror stainless steel or matt stainless steel board in three forms, beautiful and generous.

8. Automatic operation of the WNS oil and gas boiler, micro-positive pressure combustion, no need to draw fan, reduce boiler system investment, reduce boiler operating costs.

9. The WNS oil and gas boiler equipped with necessary thermal instruments, valves and various protection devices, to achieve continuous electric water regulation, automatic water level control and high and low water level alarm, low water level chain protection and other functions, automatic control of steam pressure and overpressure alarm and other functions.

Pressure. Residential steam boilers operate under very low-pressure conditions. However, a large volume of low-pressure steam can be a danger. For this reason, there are pressure controls on the boiler. Normally set at 2 P.S.I., the pressure control will shut down the system if too much pressure is sensed by the pressure control.

Difference Between Low- and High-Pressure Boilers

A boiler is an appliance designed to heat water and produce energy. The heat is applied to water in an enclosed container before being distributed throughout the system. The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces.
