Shanghai boiler manufacturer

　　Boiler manufacturerProduct Introduction

The Tian Shen brand electric heating boiler is newly designed based on the excellent performance of similar European products and in accordance with the national JB/T10393 standard. The slender vertical design enables the boiler to quickly and efficiently reach the set working temperature and pressure in a short period of time, without temperature and pressure fluctuations even during the water replenishment process.

Good separation effect of soda water

*The built-in soda water separator solves the problem of steam carrying water in similar products. This is also a characteristic that distinguishes it from other similar products in China.

computer control

All internal pipelines and control systems of the Tian Shen brand electric boiler have been connected before leaving the factory. A one-step foolproof control system, you only need to press a button, and the boiler can operate fully automatically, greatly facilitating your use.

Vertical arrangement of top mounted electric heating elements

The top mounted vertical arrangement of electric heating elements enables the scale attached to the electric heating elements to quickly peel off and detach under the action of thermal expansion and contraction, and be discharged through the drain pipe. Thereby extending the service life of the electric heating element.

A boiler is an energy conversion device that inputs chemical energy and electrical energy from fuel into the boiler. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy.

The original meaning of a pot refers to a container for heating water over a fire, while a furnace refers to a place where fuel is burned. A boiler consists of two main parts: a pot and a furnace. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people's daily life, and can also be converted into mechanical energy through steam power devices, or converted into electrical energy through generators.

A boiler is an energy conversion device that can withstand a certain working pressure. Its task is to effectively convert the chemical energy in the fuel into thermal energy, thereby generating a certain amount and quality (temperature and pressure) of steam. According to the different roles that boilers play in production and daily life, they can be divided into power plant boilers, industrial boilers, and domestic boilers. Among them, power plant boilers are mainly used for power generation. With the development of science and technology and the power industry, power plant boilers are also moving towards large capacity, high parameters, and high efficiency. To ensure safe and stable production, high automation control of boiler equipment is crucial.

The boiler system mainly includes combustion system, air supply and introduction system, steam water system, and auxiliary system.

Boiler equipment should maintain steam at a certain pressure and temperature according to the needs of production load, while ensuring safe and economical operation. So, its main regulatory tasks include:

(1) The amount of steam supplied by the boiler should adapt to changes in load or maintain a given load;

(2) The steam pressure supplied by the boiler to the load is maintained within a certain range;

(3) The temperature of superheated steam and the water level in the steam drum are maintained within a certain range;

(4) Maintain the negative pressure of the furnace within a certain range;

(5) Maintain the economic and safe operation of boiler combustion;

Boiler manufacturing process flow

1. Manufacturing process flow of tube sheet

Material acceptance → Marking → Material steel seal transplantation → Cutting → Splicing → Grinding → Flaw detection → Heating → Hot pressing forming → Marking allowance line → Processing tube sheet → Stamping steel seal → Measuring outer circle for optional selection

2. Manufacturing process flow of cylinder section

Material acceptance → Marking → Material steel seal transplantation → Cutting → Splicing → Welder steel seal code → Rounding → Longitudinal seam positioning welding → Welding → Welder steel seal code → Rounding → End face and groove processing → Measurement of outer circle for optional selection

3. Manufacturing process flow of manhole device

1) Manhole cover plate

Material acceptance → Marking → Cutting → Drilling → Machining ellipses and sealing surfaces

2) Bolt

Sawing → Turning Thread Processing

3) The two are assembled and welded before installation.

4. Boiler drum manufacturing process flow

Assembly and positioning welding of drum and drum section → welding → welding with welder's steel seal code → marking the centerline of the drum body and the position line of the pre welded parts → assembly and positioning welding of the drum body and one end of the tube plate → welding → welding with welder's steel seal code → positioning welding of the pre welded parts → assembly and positioning welding of the drum body and the other end of the tube plate → welding → welding with welder's steel seal code → non-destructive testing → marking the position line of the pipe seat hole → positioning welding of the pipe seat hole → welding → non-destructive testing → marking the position line of the hole → machining the hole → removing burrs and debris → internal component assembly → sealing the manhole cover → to be assembled

5. General assembly process of boiler pressure parts

Matching → Fixing the left and right headers on specialized fixtures → Assembling and positioning welding the lower header → Placing the drum on the specialized fixture → Assembling and positioning welding the downcomer → Welding the downcomer to the left and right headers and drum → Assembling and positioning welding the water-cooled wall pipe and rear sewage pipe → Welding the water-cooled wall pipe and rear sewage pipe → Inserting and positioning the smoke pipe and tension support piece → Welding the smoke pipe and tension support piece (expansion) → Leveling the smoke pipe → Removing debris inside the drum and header → Closing manholes and hand holes, etc. → Water pressure test → Painting

6. After the final assembly of each component of the boiler, it is packaged and stored or directly sent to the user.

The general process is the overall process, not any specific aspect. You are referring to a part of biological treatment. There are also physical treatment, physicochemical treatment, chemical treatment, and even water engineering. Most of the biological processes are A/O processes and related processes that have been differentiated, such as SBR process, oxidation ditch process, biological pond process, biochar tower, biological filter tower, etc
